What is often considered the busiest travel day of the year has arrived for Long Islanders and the rest of the country.

According to AAA, a record 38.7 million people are expected to travel at least 50 miles for Thanksgiving. The organization predicts 4.7 million people will take to the skies for the holiday and New York-area airports are expecting almost 3,500 takeoffs and landings Wednesday.

Long Islanders who arrived early at MacArthur Airport were pleasantly surprised to find no long lines and all flights on time.

For those traveling by car, AAA urges drivers to do their homework before heading out. With gas prices continuing to increase, the organization says travelers can save a significant amount of money by researching where the cheapest prices are. AAA also says drivers should leave as early as possible to avoid delays.

The Long Island Rail Road will have nine extra eastbound trains for travelers between 2 p.m. and 4 p.m. Wednesday.
