Airfare Watchdog: age limit on lap kids?

Q What is the maximum age for a child to share your airline seat on your lap?

A Lap children should be 2 years of age or younger. Keep in mind that although lap children ride free on domestic flights, you'll pay 10 percent of the applicable adult fare for them on international ones. Even if you're flying on a free frequent flier ticket internationally, if the equivalent business class fare is $5,000 round-trip you'll pay $500 for your lap child.

Q I'm 6-feet 1-inch tall and will be flying from New York to San Francisco soon. Which airline should I fly on?

A JetBlue will give you the most space for your legs. Its standard seats on all flights offer 34 inches of space between seats ("pitch" in airline parlance) and its "even more room" seats offer 38 inches. United's PS Service, which flies exclusively between JFK and both San Francisco and Los Angeles, also offers extra legroom in economy class (34 inches). I find Virgin America's economy class cramped in comparison at 32 inches. The only downside to JetBlue is that it doesn't yet offer Wi-Fi on board.
