Baggage weight sanity check

If your itinerary has a codeshare, the operating airline's rules govern your bags — the airline on your booking screen may not be the one flying the plane.

A simple packing order

Pack heavy and over-100 ml items into the checked bag first. Keep your 1L liquids bag accessible near the top of your carry-on for screening. Anything the rules are unclear about — pads, cushions, aerosols — decide before you get to the belt, not at it.
