just to confirm-the limit now is 13hrs isnt it?
i had a connection fewmonths ago dtw sfo hnd and they wouldnt ck my bags thru because over 13hrs in sfo (it was a pain lugging them)
the rep tried to do it manually but was unable to and a supervisor confirmed the system wouldnt let them do it as over 13hrs-i just wanted to confrrm
this is the actual number as it seems tochange now and again(is it 12 or 13hrs)
thanks

reason i ask is that the flights i want to take have 12hrs 43mins connection time in sfo..
