The airfare guys must be back from summer vacation.
On Friday, United Continental Holdings hiked fares by $4 to $10 roundtrip, the first hike attempt the industry has tried since late April.
According to FareCompare.com founder Rick Seaney, this is the 13th fare hike this year, with the first six having been successful. However, in the industry's attempts to raise fares since March, only one hike has stuck.
"I suspect United is probing their competition's appetite for a lift in ticket prices as airlines have some recent booking demand trend information after launching a couple of fall sales the past few weeks," Seaney wrote Friday.
Like all fare hikes, the flying public will have to wait and see if other carriers match, United Continental's move.
