Researchers say this should be the busiest travel season in five years.
Financial problems for many airlines are leading to fewer seats and higher airfare rates.
Denise Petricka, from Carlson Wagonlit Travel, also says that most people book their holiday travel plans 9-10 months in advance, so a lot of flights are already booked.
She also says that because of fewer flights, there are fewer seats, allowing for planes to fill-up quicker, effecting prices.
Petricka also says sometimes airlines offer Thanksgiving deals, which could save you a little extra money if you haven't made plans yet.
