Alaska personal item

Exact Alaska Airlines personal item size with official sources. Last verified 2026-09-10.

Quick answer

Alaska’s personal item must fit under the seat. The airline publishes no L×W×H inches or cm — official examples only (purse, briefcase, laptop bag/computer). It is free with 1 carry-on on every fare including Saver. Medically necessary items are also allowed per the carry-on page. Do not invent dimensions from United, JetBlue, or Frontier and call them Alaska’s.

Table

Field Alaska published value
Max dimensions (in) Not published — must fit under the seat (do not invent L×W×H)
Max dimensions (cm) Not published; check Alaska if a numeric limit appears later
Placement Under the seat (not overhead)
Cost Free — all fares (incl. Saver / Main / First), plus free carry-on
Weight None published for personal item
If oversized May not qualify as personal item; could count as your carry-on or need to check — no invented Alaska gate $ (United BE $75 is not Alaska)
Carry-on contrast 22 × 14 × 9 in / 45 linear; cm not published; free all fares → carry-on size
Allowed examples Purse, briefcase, laptop bag/computer (official examples only)
Saver interaction Saver = personal item + carry-on both free · Group F boarding = bin risk for carry-on
Sizer strictness Under-seat fit; airport bag sizers apply to carry-ons at 22×14×9 — personal item has no published sizer dims
Peer contrast United 9 × 10 × 17 in; JetBlue 17 × 13 × 8 in; Frontier 18 × 14 × 8 in — Alaska does not match those as official

Free vs paid

Personal item: always free if it fits under the seat.

Full carry-on: also free on all fares including Saver — unlike United Basic Economy on most domestic routes (personal-item only).

Checked: paid domestically ($45 / $55 on tickets ≥ Apr 10, 2026 for 1st/2nd) unless a waiver applies — details on Alaska baggage fees; don’t duplicate full fee tables here.

Medically necessary items: free per the carry-on page — brief allowance; not a second personal item.

Gotchas

  • No published L×W×H — blogs that list exact Alaska personal-item inches are often copying United / JetBlue / Frontier; call that out.
  • Soft bags that don’t fit under the seat may be refused as a personal item.
  • Saver Group F: carry-on still free but bins may fill late — the personal item is the reliable cabin bag.
  • Do not cite United’s $75 gate fee for a failed personal item as an Alaska rule.
  • Carry-on dims (22 × 14 × 9 / 45 linear) are not the personal-item limit.
  • Official carry-on cm also not published — don’t invent either.

Avoid fees

  1. Choose a slim under-seat bag; measure packed, not empty marketing size.
  2. On Saver (Group F), pack essentials in the under-seat bag in case the carry-on is gate-checked.
  3. Use the free carry-on on Main / First when you need more space (still free on Saver too).
  4. For checked fees, stay on the baggage fees sibling — no Amazon fee framing.

Bags that fit

Soft picks for under-seat / Alaska personal-item use. Prefer non-expanding backpacks and totes designed to fit under most airline seats. Do not claim official Alaska dimensions on product cards — Alaska publishes no L×W×H. Measure your packed bag against the under-seat space on your aircraft.

AmazonCard — Under-seat backpack for Alaska
Daypack or personal-item backpack marketed for airline under-seat use. Confirm it fits under the seat when packed — Alaska lists laptop bag / computer-style items as examples and does not publish official inches. Especially useful on Saver (Group F) when overhead fills late.

AmazonCard — Slim personal-item tote / laptop bag
Structured tote or slim laptop shoulder bag aimed at under-seat fit. Matches Alaska’s official example list (purse / briefcase / laptop bag) without inventing a size limit. Prefer non-expanding designs.

What if my personal item doesn’t fit under the Alaska seat?
