Quick rules for flying with emotional support animal in carry-on and checked baggage. Verdicts and conditions across the major aviation regions below.
Major US airlines stopped recognizing ESAs as service animals in late 2020 / early 2021 after a DOT rule change. ESAs are now treated as regular pets — must fit in an under-seat carrier, owner pays the pet fee ($95–150), and size restrictions apply. A doctor's letter no longer gets you free in-cabin travel.
ESA designation has no special legal status in the EU. Treat as a regular pet — same airline pet rules, fees, and carrier requirements apply.
No legal recognition of ESAs distinct from regular pets in the UK. Same restrictions as any pet — and cabin travel into the UK is generally not allowed (cargo only).
NOT recognised by LATAM carriers. ESAs treated as regular pets.
NOT recognised as a category by any Asian airline. ESAs are treated as regular pets — subject to standard pet import rules, cabin / cargo restrictions and quarantine. Get a certified Service Animal qualification instead, or book your pet under the carrier's standard pet policy.
NOT recognised by Australian / NZ airlines. ESAs treated as regular pets under Australian Biosecurity import rules (10 days Mickleham quarantine; cats + dogs only). NZ similar.
