DALLAS — The airlines’ latest effort to broadly raise US fares by $10 per round trip has crumbled as discount carriers like Southwest decided not to raise their prices.
After several successful price increases from December through February, two efforts to raise fares this month have died, raising questions about how much consumers are willing to pay for travel.
United and Continental started the push for another fare increase last week and were joined by Delta, American, and US Airways. But low-cost airlines never went along.
Rick Seaney, chief executive officer of FareCompare.com, said the price hike began to unravel when Delta and American rolled back the increase on some routes. He said United and Continental then gave up and canceled the increases on Saturday.
