I know I’m not the athlete I once was, but flying is getting more painful. How can I prevent it? PJL, Evanston IL

A: Leg, ankle and foot swelling happens to many passengers during long flights. When sitting in the same position for hours, blood flow slows down and blood pools in leg veins. The continued pressure leads to pain and swelling. Get up at least once an hour and walk around the aisle. Also, on long flights dress in loose clothing and footwear.

Q: Several times I’ve found myself seated next to a passenger with a very furry support dog or cat. I try to not make a fuss, but it makes me sneeze. Should I just grin and bear it or complain to get another seat? PJR, Atlanta GA

A: Save a lot of trouble by asking the flight attendant to switch seats. Do it when you first board, when changing is easier to do. Of course, in busy, crowded flights, other passengers can’t or won’t comply, so keep your hanky handy Also, earlier check with your family physician for suggested meds you can take when traveling.

I regularly go between the two cities on business and to visit family. Getting fed up with the ever-rising air ticket prices, security lines and flight delays. Do you think train service is just as efficient, cost-effective or even better? PJL, Long Island NY

A: Before you make your next travel plans, check online sources for the latest in Amtrak service between those cities. For example, a recent inquiry about a round-trip ticket by train was $70, while a flight was $240. Of course, there are other costs. Getting from your Long Island home to Penn Station by taxi, bus or local train costs an additional $50, and about the same to JFK airport.

Actually, whatever your choice, it takes a total of about four hours each way from home to destination on either train or flight. And usually costs more than twice as much to fly.

It’s embarrassing, especially when I’m in the middle seat of a very crowded aircraft. How can I prevent the gas attack or at least keep it quiet? PLJ, Denver CO

A: Gas happens to seniors and other flyers due to increasing air pressure that causes your stomach to bloat. You can reduce the pressure before you fly by avoiding carbonated beverages and fatty foods. Also, when you feel gassy, leave your seat and move around the cabin to get rid of bloating. Sip water to reduce gas attacks.
