Airlines predict a record number of Americans will fly overseas from June through August. International flights will carry an estimated 26.8 million passengers. That's a half-million more than last summer.
Domestic flights will carry about 179 million passengers -- there's no real change from last year, but they will be more crowded because airlines are reducing the amount of flights.
So planes will be full and that means if your flight is canceled due to weather, good luck getting another flight.
