You'll have to ask a dog if the cargo hold was comfortable few passengers have ridden down below except for those passengers that are dead and in a casket.
It's about time these people that insist pm bringing there little "Foo-FOO" dog into the cabin with them for emotional support always was crazy.
If a person can't travel without thie doggie in their lap those person ought to really be staying at home in bed and have foo-foo with them in bed. bark
I was somehow locked inside a SouthWest 737 lav one time. No big deal I just told the flight attendant I was fine and to advise the Capt to complete the flight and have maintenance come on board and open the door for me. NO PROBLEM
25 years ago flying a 747 from Shanghai to Tokyo I had a ground speed of 790 knots for nearly an hour while South of Japan heading to towards Narita.
Because of that extreme ground speed I had to begin my descent 210 miles from our destination.
