We have been offered a flight at the end of a multi trip which goes Washington to Newark to Dublin; all on United, we clear emmigration in Washington and bags booked through. Is 40 mins enough time to make connection? seems very little but responses to similar qestions are conflicting, some yes, some no. Tried to find out the terminals involved, not much luck, according to United's own website they have a 'dedicated' hub but still doesn't explain if we need to cghange terminals, either way no guarantee I suppose. All info much appreciated. We have to book all our flights this week.
