P.L., Memphis TN: This senior citizen requires help to get through the airport to check-in and to my flight. I always tip the airport employee who pushes my wheelchair.

Once aboard, a flight attendant helps me get settled in my seat and my carry-on into the overhead. Then, for bathroom trips, I’m escorted up and down the aisle. Should I tip for those services?

A: The average flight attendant’s salary is $45,000 a year, plus benefits and free flights. The airport employee earns about half of that amount. That said, if you feel the attendant has been very helpful during the flight, while being escorted off at your destination, a gift of from $10 and up is appropriate.
