Pre-Christmas flights to MIA this busy already?!
I guess so. Although I've had to pay vastly inflated prices in July (to pretty much all North American destinations), I've never found Christmas too bad. Four years ago I got LHR-ORD-BNA-ORD-LHR for £2k, out in F, back in CW. Granted that was right in the middle of the downturn and that was sale fare.
We'll just got via ORD, which seems to be reasonably priced.
