I'm trying to plan a trip for my friends and I this summer. We're a group of 5 and we'd really like to visit Berlin. There's just one problem: all the flights from St. Louis-->Berlin are $1500 or higher, which seems insane to me. I've tried doing the "Name Your Price" thing multiple times, checking on Tuesday afternoon, etc. It seems this price just isn't budging. Ideally I'd like to be around $1100-$1200, as that's how much my airfare was when I visited London and Tokyo on trips in previous years.
Is there a cheaper way to visit Germany, and then possibly fly or take the train to Berlin that will be more cost effective? My ideal time frame would be any week in July, or early August (we have a teacher who can only travel in the summer).
Thanks for your help!
