luckily all flights are CO flights- i'd assume even at IAH- they'd be in the same terminal. assuming i print out all boarding passes before hand, there won't be a need for me to exit security etc...just hop off the plane, and walk over to the new gate?
although i'd rather not have to find out- i'm curious, if i miss the iah-aus leg, will CO allow me to just sit and wait for the IAH-LGA leg and not cancel teh remainder of my legs?
*edit*****
just checked the gates etc of previous flights- for the Aus part it's the same plane, so no issues there- the only concern is the first transfer- i have to go from IAH term c (gate e6) to term C gate c34......in 40 mins...hmmm (more likely 20mins)
