Best Carry-On Luggage for Allegiant Airlines (2026): 5 True-Size Picks

Our pick for the ideal Allegiant Airlines carry-on is the Samsonite Omni PC Carry-On Spinner for most travelers. Its published exterior dimensions of 22 × 15 × 9.75 inches sit inside Allegiant’s paid carry-on limit of 22 × 16 × 10 inches, and the polycarbonate shell uses Allegiant’s extra width without maxing out depth. If you want a simpler value hardside, look at the American Tourister Stratum 2.0. Prefer the lightest empty weight on this list? The American Tourister Airconic is our pick.

Allegiant currently allows a paid carry-on up to 22 × 16 × 10 inches and a free personal item up to 18 × 14 × 8 inches. Wheels, handles, pockets and decorations count toward the measurement. Allegiant does not publish a general carry-on weight limit on its baggage page. There is no “carry-on approved” label that replaces measuring the full exterior, so compare published overall dimensions — not the marketing size in the product name — with Allegiant’s official baggage policy before you fly. Rules below were verified September 24, 2026.

Our Top Allegiant Carry-On Picks

How We Selected the Best Allegiant Carry-Ons

We evaluated each suitcase against the criteria travelers care about most when packing for Allegiant:

• Complete exterior dimensions, including wheels, handles, pockets and decorations
• Fit within Allegiant’s published 22 × 16 × 10-inch ceiling when unexpanded
• Whether the bag uses Allegiant’s 16-inch width or stays closer to a multi-airline ~22 × 14 × 9 profile
• Expansion risk once depth approaches 10 inches
• Empty weight and shell or fabric strength
• Wheel and handle quality
• Interior packing features and useful exterior pockets
• Whether the product fills a distinct traveler need rather than repeating the same bag five times

A manufacturer’s “carry-on” or “22-inch” label did not earn a higher ranking on its own. We compared advertised overall dimensions with Allegiant’s published rules and noted where expansion or packing bulge could still cause problems. This guide is research-based from published specifications; we did not physically test these products for this article.

What Size Carry-On Is Best for Allegiant Airlines?

Choose a packed suitcase that stays at or below 22 × 16 × 10 inches including wheels and handles. You do not need to use every inch.

Allegiant’s 16-inch width is more generous than the common U.S. ~22 × 14 × 9 pattern. Bags around 22 × 15 × 9.5–9.75 inches can use that Allegiant capacity, while bags closer to 22 × 14 × 9 travel better if you also fly American, Delta and similar carriers. See our how to choose the right luggage size guide for trip-length packing context, and browse more carry-on reviews.

Do not rely on the size in the product name. A “20-inch” or “22-inch” case can measure differently once wheels and handles are included.

Do Wheels and Handles Count on Allegiant?

Yes. Allegiant states that exterior measurements include wheels, pockets, handles and decoration. Compare Allegiant’s 22 × 16 × 10-inch limit with a manufacturer’s overall or external dimensions, not packing-only or case-body measurements.

Does Allegiant Have a Carry-On Weight Limit?

Allegiant does not publish a general carry-on weight maximum on its baggage page. You still need to lift the bag into the overhead bin yourself, so a lighter empty suitcase remains easier to handle — especially on ultra-low-cost itineraries where every pound of packing discipline helps.

Is Hardside or Softside Better for Allegiant?

Neither is automatically better. Softside cases usually add exterior pockets and some flexibility, but overstuffing can increase their real dimensions. Hardshells offer rigid protection and often a divided interior, but a case already near 10 inches deep has little ability to compress in a baggage sizer.

For Allegiant, verified dimensions and packed size matter more than shell type — and remember that the carry-on itself is paid, so the bag only makes sense when overhead-bin space is worth the fee on your route.

Should You Buy a Full 22 × 16 × 10-Inch Carry-On?

Usually not if you regularly fly tighter U.S. airlines.

Allegiant’s width is useful for Allegiant-heavy travelers. A suitcase that leans on the full 16-inch width can be less practical on carriers closer to a 22 × 14 × 9-inch ceiling. If Allegiant is your main airline, a bag like the Omni PC or Stratum 2.0 can use that capacity. If you switch carriers often, prefer something nearer 22 × 14 × 9 — such as the Briggs & Riley Essential 22 compressed, or the LOVEVOOK 20-inch softside. Compare also our best carry-on luggage for Frontier Airlines and Southwest Airlines guides (wider 24 × 16 × 10 ceilings) and our American Airlines picks for tighter U.S. limits.

Are Expandable Carry-Ons Safe for Allegiant?

Yes when used unexpanded, provided their base dimensions comply. Expansion itself can make an otherwise suitable bag oversized.

The Omni PC, Stratum 2.0 and Briggs & Riley Essential 22 all expand. Keep expansion closed for Allegiant boarding and compare the packed depth with the 10-inch limit before you fly.

Allegiant Carry-On vs Personal Item

Use the free personal item when you can comfortably pack within 18 × 14 × 8 inches. Add a paid carry-on when overhead-bin space is worth the route-specific fee.

A personal item can work for a weekend or minimalist trip. A carry-on is more practical for bulky shoes, cold-weather clothing, longer journeys or family gear. Pre-purchase carry-on fees are usually lower than airport pricing — check your Allegiant booking before you buy bags at the airport.

1. Samsonite Omni PC Carry-On Spinner

Best Overall Allegiant Carry-On

The Samsonite Omni PC is our best overall Allegiant pick because it combines verified exterior dimensions that use Allegiant’s width with a scratch-resistant polycarbonate shell and spinner wheels.

Published overall dimensions are 22 × 15 × 9.75 inches, including wheels and handles, with an empty weight around 6.8–7.05 pounds depending on the listing. Those unexpanded measurements sit under Allegiant’s 22 × 16 × 10-inch ceiling and leave a little width margin versus the airline’s 16-inch maximum.

Ignore the “20-Inch” marketing name on many retail pages. The overall height is 22 inches once hardware is included — exactly the kind of naming trap Allegiant travelers need to avoid.

The main caveats are depth and expansion. At about 9.75 inches deep, there is little room for packing bulge. Expansion can push the case past Allegiant’s 10-inch depth limit, so keep the expansion zipper closed for boarding. Also confirm the exact carry-on Amazon variant before buying; product pages sometimes group sets and checked sizes.

Best for: Allegiant travelers who want a durable polycarbonate spinner that uses the airline’s 16-inch width without maxing out height or depth.

Pros

• 22 × 15 × 9.75-inch overall dimensions fit Allegiant unexpanded
• Uses Allegiant’s wider allowance better than a strict 14-inch case
• Micro-diamond polycarbonate shell with spinner wheels
• Side-mounted TSA locks on typical listings
• Makes the “20-inch name vs 22-inch overall” lesson clear

Cons

• Very little depth margin at ~9.75 inches
• Expansion can exceed Allegiant’s 10-inch depth limit
• 15-inch width is less ideal as a multi-airline “fit everything” bag
• Exact Amazon carry-on variant must be verified

2. American Tourister Stratum 2.0 Carry-On

Best Value Allegiant Carry-On

Travelers who want an affordable ABS hardside spinner without premium pricing should consider the American Tourister Stratum 2.0.

Published overall dimensions are 22 × 15 × 9.5 inches, with an empty weight of about 7.3 pounds. The textured ABS shell, spinner wheels and 1-inch expansion zipper give a straightforward short-trip layout for Allegiant.

Those base dimensions fit Allegiant’s current allowance, with half an inch of depth remaining. Opening the expansion can therefore make the bag too deep for Allegiant’s 10-inch limit. Like the Omni PC, the 15-inch width uses Allegiant capacity but is wider than a multi-airline ~14-inch preference.

Best for: Occasional Allegiant travelers who want a practical value hardside for short trips.

Pros

• 22 × 15 × 9.5-inch exterior fits Allegiant unexpanded
• ABS hardside at a value-oriented price tier
• Spinner wheels and ergonomic trolley grip
• Max-capacity interior with mesh pocket and tie tapes
• Clear 1-inch expansion you can simply leave closed

Cons

• Heavier empty weight than the Airconic
• 1-inch expansion can exceed Allegiant’s depth limit
• ABS shell is generally less flexible than polycarbonate under impact
• 15-inch width is less multi-airline friendly

3. American Tourister Airconic Carry-On

Best Lightweight Allegiant Carry-On

Choose the Airconic when empty weight matters more than maximizing Allegiant’s depth.

Manufacturer-published overall dimensions are approximately 21.7 × 15.8 × 7.9 inches, with an empty weight of about 4.4 pounds. The polypropylene shell stays well under Allegiant’s 10-inch depth and still uses most of the airline’s 16-inch width.

The trade-off is packing volume. At roughly 7.9 inches deep, you give up capacity compared with the Omni PC or Stratum 2.0. Listings typically note the case is not expandable. Confirm color and availability on Amazon; some Airconic carry-on ASINs rotate in and out of stock.

Best for: Travelers who want the lightest shortlist option and a shallow hardshell that clears Allegiant’s depth limit with room to spare.

Pros

• About 4.4 pounds empty — lightest on this list
• 21.7 × 15.8 × 7.9-inch exterior fits Allegiant with depth margin
• Polypropylene hardshell with spinner wheels
• Typically not expandable, so depth stays predictable
• Recessed TSA lock on many listings

Cons

• Shallower depth means less packing volume
• 15.8-inch width is still wide for multi-airline ~14-inch limits
• Amazon availability can be uneven by color/ASIN
• Less “Allegiant capacity” use than a deeper 9.5–9.75-inch case

4. Briggs & Riley Baseline Essential 22

Best Premium Allegiant Carry-On

Choose the Briggs & Riley Baseline Essential 22 when organization, lifetime repair support and multi-airline fit matter more than minimum empty weight.

Published exterior dimensions are 22 × 14 × 9 inches compressed and up to 11.5 inches expanded, with an empty weight of about 10 pounds. Compressed, it fits Allegiant with width and depth margin — and doubles as a stronger multi-airline bag than the wider Allegiant-capacity hardsides.

The CX expansion system is useful after landing or when checking a bag, but a fully expanded 11.5-inch depth exceeds Allegiant’s 10-inch limit. Keep it compressed for boarding. Softside ballistic nylon construction, spinner wheels and Briggs & Riley’s lifetime repair promise define the premium trade-off against the heavier empty weight.

Best for: Frequent travelers who want a premium softside that fits Allegiant compressed and still works on tighter ~22 × 14 × 9 airlines.

Pros

• 22 × 14 × 9-inch compressed exterior fits Allegiant with margin
• Strong multi-airline profile vs wider Allegiant-capacity bags
• CX expansion when you need more room off the aircraft
• Ballistic nylon softside with spinner wheels
• Lifetime repair support for normal-use damage

Cons

• About 10 pounds empty — heaviest on this list
• Expanded depth up to 11.5 inches exceeds Allegiant’s limit
• Premium price tier vs value ABS/PC options
• Does not maximize Allegiant’s 16-inch width

5. LOVEVOOK 20-Inch Softside Carry-On

Best for Business Travel on Allegiant

Choose the LOVEVOOK 20-inch softside when laptop access and exterior organization matter more than filling Allegiant’s full width.

Published overall dimensions are 21.25 × 13.78 × 9 inches, including wheels, with an empty weight of about 6.7 pounds. Those measurements sit comfortably inside Allegiant’s 22 × 16 × 10-inch limit and also align with many tighter U.S. carry-on profiles.

The softside polyester body adds a dedicated laptop compartment, multiple front pockets, spinner wheels and a built-in TSA lock. That layout is useful for short business trips where you want documents and a laptop without opening the main compartment. Avoid overstuffing exterior pockets, which can increase packed depth. For more detail, see our LOVEVOOK carry-on luggage review.

Best for: Business and weekend travelers who want laptop-friendly organization and multi-airline dimensions on Allegiant itineraries.

Pros

• 21.25 × 13.78 × 9-inch exterior fits Allegiant with margin
• Separate laptop compartment and quick-access front pockets
• About 6.7 pounds empty
• Spinner wheels and integrated TSA lock
• Strong multi-airline size profile

Cons

• Does not maximize Allegiant’s 16-inch width
• Main compartment can feel smaller than wider hardsides
• Overstuffed exterior pockets can increase packed depth
• Softside shell offers less rigid impact protection than polycarbonate

Allegiant Carry-On Buying Considerations

Measure the full outside dimensions

Include wheels, handles, pockets and decorations. Interior-only dimensions can make luggage look artificially small compared with how it lines up with an airport sizer.

Decide Allegiant-capacity vs multi-airline

Use Allegiant’s 16-inch width if Allegiant is your main carrier. Prefer ~22 × 14 × 9 if you also fly tighter U.S. airlines.

Avoid expanding before boarding

Expansion is helpful after landing or when checking a bag. An expanded suitcase could exceed Allegiant’s 10-inch depth limit while its compressed counterpart would have qualified.

Remember the carry-on is paid

Allegiant includes a personal item, not a free overhead carry-on. Buy a suitcase only when the paid bag is worth it for your itinerary, and pre-purchase when possible.

Ignore “22-inch” naming alone

Marketing sizes are not airline measurements. Compare published overall exterior dimensions — height × width × depth including hardware — with Allegiant’s 22 × 16 × 10-inch rule.

Final Verdict: What Is the Best Carry-On for Allegiant Airlines?

The Samsonite Omni PC Carry-On Spinner is our overall winner for Allegiant. Its 22 × 15 × 9.75-inch exterior fits the airline’s published 22 × 16 × 10-inch limit unexpanded and uses Allegiant’s wider allowance without maxing out height or depth.

Get the American Tourister Stratum 2.0 if you want a simpler value ABS hardside. Choose the Airconic if empty weight is the priority. Frequent travelers who need premium softside organization and multi-airline fit should look at the Briggs & Riley Baseline Essential 22 (compressed). Business packers who want laptop access should consider the LOVEVOOK 20-inch softside.

Regardless of which suitcase you choose, measure the fully packed bag’s overall dimensions against Allegiant’s current rules before you board, and confirm whether a paid carry-on is worth the fee versus staying with the free personal item.
