Spokeswoman Andrea Huguely said Monday that the decision was an economic one. She says blankets will remain complimentary in premium-class cabins and in all cabins for other international flights.
The airline will sell a blue fleece blanket with an inflatable neck pillow in a clear zippered pouch, and will throw in a coupon for $10 off a $30 purchase at Bed, Bath and Beyond.
JetBlue and US Airways charge $7 for a blanket-and-pillow set, with US Airways adding eye shades and earplugs.
American parent AMR Corp. lost $1.47 billion last year -- and $3.59 billion in the past two years -- as traffic fell during the recession and competition limited American's ability to raise fares.
