I really appreciate the information from you both - I dont really have too many recovery options from NYC and its an expensive place to be stuck! Looking on the seat map for UAL875 SEA-NRT it looks the best out of all the UAL flights to NRT that day - problem is getting there first thing in the am - are any of you able to take a peak at the loads for UA1158 CLE-SEA on Oct 01? Again - I really appreciate the help and info you have already given me - I think based on Ottolillienthal's comments I am going to cross the EWR flight off the list!
Cheers and thanks again
