The website has been acting up for me for the last few hours. I'll try to check prices for an upcoming flight (I've been trying to pick an exact city pair to go from New Orleans to Baltimore, and I have some "slack" in my travel plans so I'm able to work with one of two or three days). However, I keep getting sent "in a loop": I'll enter the city pair/dates and then get kicked back to enter those again.

And again.

And again.

On two separate browsers (Internet Explorer and SRWare Iron).

I'm getting this error message as well:

Oh no! We’re sorry, but there was a problem processing your request. Please try again.#100900R
Does anybody know what's up?
