United Air Lines raises fares $4 to $10 per round trip

United Air Lines has hiked domestic round-trip fares by $4 to $10, depending on the route, marking the seventh proposed rate hike of the year.

So far this year, only three of those hikes initiated by individual airlines have been matched by major competitors. When most competitors refuse to match the hikes initiated by individual airlines, the carriers usually drop the hike.

It is unclear yet whether United’s competitors will match the latest hike, said Rick Seaney, chief executive officer of the travel site Farecompare.com, which keeps track of such increases.

He noted that oil prices have increased recently because of rising tensions in the Middle East, after briefly dropping below $80 a barrel in June.

In the past few years, most fare-hike attempts have been adopted throughout the industry only when they are matched by Southwest Airlines, the nation’s largest low-cost domestic carrier.
