Airline Carry-On Policy Changes in 2026

Airline carry-on policies move slowly — until suddenly they do not. 2026 has seen a cluster of enforcement tightening, fare restructuring, and a handful of genuine limit changes that affect how travellers pack. Here is what has changed, which carriers drove the changes, and what the trends suggest about where cabin luggage policy is heading.

Ryanair: Tighter Enforcement, No Change to Limits

Ryanair did not change its published carry-on dimensions in 2026 — the rule remains a 40×20×25 cm bag (the small cabin bag, free on all fares) or a 55×40×20 cm priority bag for passengers on Plus, Flexi, or those who purchased priority boarding. What changed is enforcement intensity.

Following a period in which post-pandemic passenger volumes led to looser gate enforcement, Ryanair reintroduced systematic bag gauging at a number of its busiest European bases from early 2026. Sizers — the metal frames at the gate that a bag must fit through — are now more consistently in use at Stansted, Dublin, Bergamo, and Palma de Mallorca. Passengers caught with oversized bags at the gate face a fee that in 2026 stands at €69 if paid at the gate, compared to €10–25 if pre-purchased online.

The practical implication: if you regularly fly Ryanair with a bag that is borderline on dimensions, the risk of a gate charge has increased meaningfully. The published policy has not changed, but the probability of enforcement has.

EasyJet: Carry-On Now Tied to Fare Tier More Strictly

EasyJet restructured its cabin bag inclusions in late 2025, and the changes took full effect in early 2026. Under the new structure:

• Standard fares include one small under-seat bag (45×36×20 cm) only.
• FLEXI fares include a large cabin bag (56×45×25 cm) in addition to the small bag.
• Up Front and Extra Legroom seat purchases include the large cabin bag.

The change effectively removed the large carry-on allowance from the cheapest EasyJet tickets that previously included it, pushing passengers toward either paying for the large bag (approximately £8–25 per flight depending on route and booking timing) or purchasing a higher fare tier. This mirrors the trajectory Ryanair set in earlier years.

Wizz Air: Weight Limit Now More Strictly Weighed

Wizz Air's carry-on policy (a 40×30×20 cm bag, free; a 55×40×23 cm larger cabin bag for Wizz Priority passengers) has not changed in dimensions. However, spot checks on the 10 kg weight limit for the larger bag have become more common at Eastern European hubs in 2026. Historically, weight checks at Wizz Air gates were rare; in 2026 they have become standard at Budapest, Bucharest, and Warsaw.

Spirit Airlines: Personal Item Size Remains, Carry-On Fee Increases

Spirit Airlines, operating within Chapter 11 restructuring in late 2024 before its acquisition completed in 2025, has settled into a new fee schedule for 2026. The carry-on bag fee (for the full-size overhead bin bag) has increased to $79 when purchased at the gate, up from $65 the prior year. Online advance purchase of the carry-on remains the significantly cheaper option at $35–55 depending on timing. The personal item (which must fit under the seat and measure no more than 45×35×20 cm) remains free on all fares.

Frontier Airlines: New Bundled Fare Tiers Lock In Bag Fees

Frontier restructured its fare bundles significantly for 2026. The bare-bones "Basic" fare has become stricter: the personal item allowance is the only included item. A standard carry-on bag now requires either a bundle upgrade or a separate fee. The new "Go" bundle includes the carry-on and a checked bag; the "GoWild" pass includes a carry-on in the all-in fare. For travellers who previously bought Basic and paid for just the carry-on, the fee has risen and the process of adding it at checkout has been made slightly more convoluted — a common tactic to push passengers toward bundles.

Delta, United, American: No Changes to Core Carry-On Rules

The three major US network carriers made no material changes to carry-on dimensions or basic allowances in 2026. All three continue to allow one carry-on bag (that fits in the overhead bin) and one personal item for all passengers except Basic Economy, where the carry-on fee remains in place on Delta and American. United maintains its policy of allowing Basic Economy passengers a personal item only on most domestic routes.

Air France and KLM: Linear Dimension Now Published More Prominently

Air France and KLM have not changed their carry-on limits (55×35×25 cm and 55×35×25 cm respectively) but both airlines updated their website presentation in 2026 to display the linear dimension total (115 cm) more prominently alongside individual measurements. This is a disclosure improvement rather than a policy change, but it has led to some travellers discovering that their bags — which pass on individual measurements — fail the linear test.

Trends Driving 2026 Carry-On Policy

1. Fare unbundling continues

The dominant trend across low-cost and ultra-low-cost carriers globally is the continued disaggregation of what was once a bundled ticket price. Carry-on bags, once a basic inclusion, have become a paid add-on at an increasing number of carriers. The logic is straightforward: travellers anchor on the headline fare price and are willing to pay for extras they perceive as optional. Carry-on bags are the highest-value ancillary after seat selection.

2. Enforcement investment

Budget carriers are investing in gate technology and staff training to close the gap between published and enforced policy. Digital boarding pass readers can now flag passengers for bag checks based on fare class; sizers are being re-introduced at gates where they had been informally retired. For airlines, each gate-caught oversized bag generates more revenue than a pre-purchased upgrade — a structural incentive to enforce.

3. Overhead bin capacity pressure

On many short-haul routes, overhead bin space is mathematically insufficient to accommodate a full-size carry-on for every passenger. Airlines are responding in two ways: some enforce limits more strictly to reduce the number of bags; others are experimenting with valet-style gate-checking programs that check bags for free but remove them from the overhead bin entirely, speeding boarding.

4. Regional variation is widening

While European budget carriers are tightening, some Asia-Pacific full-service carriers have maintained or modestly increased carry-on allowances as a competitive differentiator. Gulf carriers (Emirates, Qatar, Etihad) continue to offer generous allowances. The global picture is not uniformly restrictive — it is diverging, with budget carriers becoming stricter and full-service carriers maintaining or gently improving allowances for premium-class passengers.

What This Means for Travellers in 2026

• Check your specific airline and fare class before every trip. Generic advice about carry-on allowances is increasingly unreliable as policies diverge.
• Buy any bag add-ons at booking, not at the gate. Gate fees are now 2–4× the advance online price at most budget carriers.
• Measure and weigh your bag before flying budget. A bag that passed last year may be caught this year if enforcement has tightened at your departure airport.
• Consider full-service carriers for longer trips. The cost of a carry-on add-on on a budget carrier often narrows the fare gap with a network carrier that includes the allowance.

The direction of travel is clear: carry-on allowances are becoming a product feature that airlines charge for, not a baseline right. Staying current on the specific rules of each carrier you fly is no longer optional — it is the price of travelling carry-on only.
