I'm assuming that all should be fine for connecting at IAH from JAX to DEN in 1hr. 20 min. Does anyone have an idea what terminal United might use for this flight? If it helps, we will be arriving at IAH on an ExpressJet RJ and departing for DEN on a 737-900. At least that's the plan for now...United has changed my itinerary 5 times already...ughh.
your flight from JAX-IAH will arriving at Terminal B, (may even arrive at Terminal C), your departing flight to DEN will either depart from Terminal C or Terminal E.
