A couple of East Coast friends and I do a ballpark run or two every summer (BOS last year, SFO and Comiskey this year, CLE and/or DEN next year) and, I can tell you: we use one airline or another -- we're very price-sensitive -- but Priceline consistently yields a heck of a deal on multi hotel rooms, in nice properties, in whatever city we end up in. I think it's a natural tie-in for them.

Pluswhich, UA's big problem right now isn't attracting leisure flyers headed for the left-field bleachers on weekends... it's the business travelers who're deserting 'em in droves. Would your campaign line up with their business goals?
