Ugh Brutal! I have no issues with DL's service and love the wifi --but their FFp program is a joke as we know it and I'd be earning miles in vain or so I can blow 50,000 miles on a domestic trip as that's all that's available.
Unless I see something else, it appears DL fits me best and maybe AA if I know they have wifi. I really wish UA/CO would add this sooner rather than later.
