Yeh, Im on one ticket with expedia, I bought it as MAN > SFO.... I know I gotta grab it, drag it though customs and dump it on the "onward" conveyor belt.. but I was concerned that If bmi don't do thru-checking of bags that I'd have to collect it and then go outside, change terminals and then go through check in with United.... and as im flying business with bmi I shouldn't have to pay more for traveling with ski's.. where as united only allow you to take 2 bags in domestic 1st I read...
