Morning (In US Anyway).
We are on a RS Tour next June. The booking window for air transportation is just starting to open up. Not every site/airline has availability yet but I have noticed something interesting on the United Airlines site. The price for Premium Economy is twice as much when I'm logged in with my account versus when I'm not. Interesting.......
I am also checking pricing for a June trip to the UK. American Airlines is showing just premium ticket sales this morning. Not sure what is going on with the site, I checked the lowest fare and class from STL to LHR before searching. Pricing seems way high right now for the window just opening. I usually buy around September/October for my next summer flights but not at these prices. I am having sticker shock! I am going over to Delta and United and see what pricing they have.
And I found the above yesterday. You don't say where you're flying from/ to. Good luck!
