Do beer bottles explode on an airplane?

Answer 1

No. I flew from Germany to Canada with 10 full beer bottles in my check in luggage for a friends birthday and all of them were okay.

Answer 2: In some old airplanes glass bottles placed on the overhead compartments tend to break. In newer airplanes it does not usually happen but it is allwys recommended that you place glass bottles under the seat in front of you due to safety reasons.

Answer 2

Things in sealed containers can burst or leak. The cabin is pressurized and things in there seldom have a problem. Items in luggage may not be in a pressurized area and the expansion due to lower air pressure can be a problem. I would not think that a bottle would be an issue, unless it is carbonated. I k now that many times my liquids (saline for contacts) often leak, so have learned to pack them in plastic bags.
