With you on this one. We travel in August out of Philadelphia and it seems airfare is up 40-50%. We kept watching and looking to see how many seats were left. The day before my wife was about to bite the bullet and purchase, I checked an old closed credit card for mileage.
I had exactly 50 extra miles left after purchasing 2 business class tickets.
Been watching airfare since purchase and it seems I bought at the lowest mileage. I used 62,500 miles and today it's over 100,00 miles.

Hope it goes down for you.
