If you're flying out of town this holiday weekend, New York City Transit is offering a special treat.

The Q70 bus is free Thursday and Friday between the main terminals at LaGuardia Airport and the subway stop at 74th Street-Roosevelt Avenue in Jackson Heights.

Passengers can also hop on board at the Woodside Long Island Rail Road station.

Transit officials hope the bus link will help alleviate traffic congestion.

There's some good news for drivers, too. There is free parking at the P10 parking lot Friday. But get there early - it's on a first come, first serve basis.

Friday is expected to be the busiest travel day of the season at LaGuardia.
