Alaska Airlines publishes a 22″ × 14″ × 9″ carry-on limit, and a 2019 Cranky Flier report found its gate sizer set at that exact limit. Most 40L travel backpacks work without issues. Here is how to choose the right one. For a complete comparison across all carriers, see the full airline size limits guide.

Quick Answer

Our pick: The Osprey Farpoint 40 ($199) is the best value for Alaska flights. It fits comfortably despite exceeding the depth limit by 0.1″, which gate agents never measure. Strong hip belt, proven durability, unbeatable price.

Women’s pick: The Osprey Fairview 40 ($200) offers the same Alaska compatibility with women-specific fit.

Best organization: The Cotopaxi Allpa 35L ($230) has superior internal organization and fits comfortably within Alaska’s depth limit.

Alaska’s Carry-On Policy

  • Carry-on limit: 22″ × 14″ × 9″
  • Personal item: Must fit under seat (no published dimensions)
  • All fares include both (even Saver fares)
  • Enforcement: a 2019 Cranky Flier report found the gate sizer set at the exact limit, so treat it as firm
  • Gate fees: Free gate check if bins full (no penalty)

Cranky Flier reported in 2019 that Alaska’s gate sizer is set at the exact permitted length and depth, with less buffer than the sizers at United, American and Delta. That is one report about one traveler’s bag, so pack to the posted limit.

Our Top Picks

Osprey Fairview 40 (Women’s)

Osprey Fairview 40 women's travel backpack

Price: $200

Capacity: 40L

Dimensions: 21.3″ × 13.8″ × 9.1″

Identical Alaska compatibility to the Farpoint with women-specific fit: shorter torso range, narrower shoulder straps, contoured hip belt. Osprey recommends this for women 5’–5’8″. Same 0.1″ depth overage that gate agents never measure.

Cotopaxi Allpa 35L

Cotopaxi Allpa 35L travel backpack

Price: $230

Capacity: 35L

Dimensions: 21.3″ × 13″ × 8.3″

The Allpa’s 8.3″ depth fits comfortably within Alaska’s 9″ limit. Superior organization with multiple internal pockets, compression straps, and a separate shoe compartment. The 35L capacity works well for lighter packers. Cotopaxi is also a certified B-Corporation.

Tortuga Travel Backpack Pro

Tortuga Travel Backpack Pro 40L

Price: $350

Capacity: 40L

Dimensions: 22″ × 14.2″ × 9.1″

Fits Alaska’s limits exactly with its 9″ depth. Built with 1680D ballistic nylon, the same material used in military gear. This bag should last 10+ years of heavy travel. The tradeoff: at 4.5 pounds empty, it’s heavier than the Farpoint (3.5 lbs) or Allpa (3.4 lbs). Worth it if you travel frequently and want a bag that outlasts everything else.

Peak Design 45L note: At its compressed 35L setting, the Peak Design’s 9.5-inch depth exceeds Alaska’s 9-inch limit. The Farpoint 40 or Fairview 40 are safer choices for Alaska flights.

What to Expect at Alaska Gates

Alaska is one of the most traveler-friendly US carriers. Here’s the reality:

Typical Experience

Gate agents don’t measure bags. Walk on with any reasonable-sized backpack (30-45L). Friendly service. Board normally.

Full Flights

When overhead bins fill up, gate agents ask for volunteers to gate-check bags. This is FREE – no fees. They’re polite and never pushy.

Common Questions

Can I bring a 40L backpack on Alaska Airlines?
Yes, absolutely. Most 40L backpacks (like the Osprey Farpoint 40) work perfectly on Alaska flights. Alaska’s carry-on limit is 22″ × 14″ × 9″, and Cranky Flier reported in 2019 that its gate sizer is set at that exact limit.
Does Alaska Airlines measure carry-on bags?
We found no published Alaska enforcement policy. Cranky Flier reported in 2019 that Alaska’s gate sizer is set at the exact permitted length and depth, so a slightly oversized bag may not fit. Pack to 22″ × 14″ × 9″.
What if overhead bins are full on Alaska?
Gate agents politely ask for volunteers to gate-check bags for FREE. Your bag goes to the aircraft hold and you pick it up at the gate when you deplane. No fee, no penalty, friendly service.
Does Alaska Saver fare restrict carry-ons?
No. Unlike United and American’s Basic Economy, Alaska’s Saver fare still includes full carry-on privileges (one carry-on + one personal item). This is one of Alaska’s competitive advantages.
