We will be flying next winter to Hawaii first class. Is it acceptable to wear jeans? I want to surprise my hubby ahead of time so I don't want to tell him to wear dress pants. Actually, I don't want him to know I splurged and got those tickets ahead of time!! We will be on a U. S. Airways 319 from Columbus and a 752 from Phoenix. If anyone has flown on those 1st class can you tell me about your experience with those flights?
