We are flying to San Jose, Costa Rica from the UK next month with UA. I have sorted out the ESTAs but am interested to know what the procedures will be for the transit and whether time will be tight.
Outbound Arrive Newark 16:05 on UA9
Depart Newark 17:54 UA1082
Arrive Houston 17:44 UA1099
Depart Houston 19:20 UA004
Thank you for any help
