Q: On my last trip from NYC to London, the man next to me really reeked, obviously a heavy smoker and infrequent bather. His hair, skin, clothing and breath were putrid. I asked the flight attendant to move me, but she said all seats were filled. Is there anything I can do about it next time it happens? PLMcR, Jersey City NJ

A: Not much if all passenger compartments are full. However, if you’re in a cheap seat when the stink happens, ask if all seats in all compartments are occupied. If not, demand politely but firmly to be moved to a higher-priced seat for free.
