Be prepared - bring earplugs if you are flying Delta between Detroit and Minneapolis. Delta flies a VERY LOUD plane (MD88 model) - #deltamakingusdeaf loud. Because we flew basic economy, we were of course seated at back of plane. Decibels had to be 90+ the entire trip. I asked flight attendants for ear plugs - they didn't have any, and one attendant said he tries to never fly on MD88 planes. If I had to do it over again - I'd fly Southwest, United, anyone else - or even drive instead.
