I'm finding one-way Main cabin fares SEA/IND in August as high as $499, in September and October as high as $349--again, ONE WAY. Lowest fares I can find (Q) in Sep/Oct are $199 each direction, more typically $249. Unprecedented, as they say. Pretty sure I recall pre-pandemic never paying more than $119 for the same a month or so out.

Even SEA/CVG is getting up to $249 one way in Sep/Oct already. And a RT SEA/CVG booking I made last week for late Aug/early Sep would now cost $160 more now than when I booked it.

Glad I got a few trips booked before this trend started. It's looking more and more like a good summer for road trips and day trips from home.

But hey, I live in the PNW. That's a good thing.
