Q: What do you do if the couple in the hotel room next to yours are getting amorous at high volume and keeping you awake?

Q: What do you think of that guy who was denied boarding on his flight because he was wearing a tracksuit and had a seat in first class? What should you wear in first class?

Q: I'm going to L.A. next week for the first time. If I see a celebrity in a restaurant, is it OK to say hi? Can I ask for an autograph or photo?

Q: I fly for business much more than my boss does. Recently, we were on the same flight, and I got upgraded to first class because of my frequent-flier status. The next day, he told everyone what a miserable time he had in a middle seat in the back of the plane while I was "living it up in first class." Clearly, he expected me to offer him my seat. Should I have?

Q: I'm not a picky eater, but recently I was at a restaurant and my meal was inedible. There was way too much salt. I thought about sending it back, but it was a nice restaurant, and I didn't want to make a scene. When and how should you send food back?

Q: Recently, I've gotten quite overweight -- fitting into plane seats is now challenging. On my last flight, the guy next to me asked the flight attendant, loudly, what she was going to do about "This huge lady taking up half the space I paid for." They reseated him, but I was mortified. What can I do? Should I buy two seats?

Q: I need to take my 4-month-old baby on a cross-country flight to visit her grandparents. She'll undoubtedly cry, make bad smells, etc. What can I do to avoid the other passengers' wrath? Is it rude to even attempt this?
