Before you pack

Measure the packed bag, not the empty manufacturer size. Bulging pockets, handles and wheels can affect whether the bag fits the sizer.

At the airport

Keep documents, liquids and electronics easy to reach so you do not need to open and repack your bag during security or boarding.

If your bag is close

A close result means there may be little tolerance. Use the checker, reduce soft contents where possible, and confirm the latest rules with the airline.
