Our son and his wife don't get to travel much so we bought them tickets to fly to Calif. for a few days at Christmas. They were unable to sit together on the flight out but luckily [?] had seats together going back to MN. But a teenager in the seat behind them was vomiting during much of the flight, causing all around him to feel like doing the same! His father FINALLY suggested that he might be more confortable in bathroom, so he finally went for about 20 minutes. Wasn't it the job of the FA to escort him to the bathroom soon after he began throwing up? Is it the passengers's job to take care of this nausiating situation? The flight was not especially rough: maybe it was airline food!
