United Raising Fares Again
Not defending this, but it's certainly not unique. Fare raises have been sparse in the little while before UA raised them a couple of weeks ago, but go back the last couple of years, and you'll see lots of instances of airlines attempting to raise fares within a week or two of the last one. Yes, before the merger. That's life.
Also not clear if it sticks until every other major carrier follows. Even if one major doesn't, his will get roles back.
