A steep decline in projected air travel dragged down the overall forecast. AAA expects holiday air travel to decrease 8%, to 2.3 million travelers this year.
The group said that fliers are suffering from "fee fatigue," fed up with paying extra for services that were once included in the price of a plane ticket, such as reservation changes, checked baggage, pet travel, food, nonalcoholic drinks, and so on.

These additional fees exceeded $6 billion last year, according to the most recent figures available from the Bureau of Transportation Statistics, with $3.5 billion in baggage fees and $2.6 billion in fees for reservation changes.
The majority of Memorial Day travelers -- some 89% -- are expected to travel by car. About 31.2 million people will be on the road, according to AAA, essentially flat compared with last year.
Drivers will be feeling the impact of gas prices that have been on the rise this spring. The national average price of a gallon of unleaded gasoline notched up to $3.66 on Wednesday, the 17th consecutive day of increases. But prices are still down slightly from last year.
AAA defines the Memorial Day weekend as the period from Thursday, May 23, to Monday, May 27.
