Why you can use this page to make a decision
This page combines a direct answer with airport, airline and primary-source rules. Safety answers are not influenced by partner content or advertising.
There is no single short list for every trip
Airport security rules, dangerous-goods rules and airline policies overlap. An item may be generally permitted but still have limits on size, capacity or packing.
Power banks work differently
Do not move a power bank to checked baggage to avoid a cabin restriction. Power banks belong in the cabin and must meet the Wh limit.

What to verify before closing your bag
Baggage allowance is a combination of fare, bag type, dimensions and weight - the airline name alone is not enough.
- Confirm the fare shown in your booking.
- Measure wheels, handles and protruding parts as part of the bag.
- Keep airline baggage rules separate from airport security rules.
Who prepares the answers
Content is prepared by the PreflightMate Research Desk from structured data and official sources. We do not present ourselves as an aviation authority or airline.
Automation helps format, compare and translate data. A rule marked verified must be linked to an official source; conflicts and exceptions remain visible.
A specific airport, airline, route, destination-country rule or a security officer may apply a more restrictive requirement.
