My connection in Houston to Killeen. Male flt. Attendant not very informative. Our flt. Was late and he was instructing us. That those with close time connection will need to get off 1st. My flt. to Killeen stops boarding at 2130. We got to our gate at 2110 . This attendant snapped at me and told me I have plenty of time! And I could wait for the others. WTH really I still needed to get to another terminal. Even your app. Notification told me it takes 17 minutes to get to my next gate. By the time I got off the plain I had 15 minutes to run to my connection. Needless to say I made 1 minute before they closed the gate. If I would have listened to that attendant and waited, I would have NOT made my connection. Note: My trip is to see my son off. He is in the Army and deploying for 9 months this weekend. I would not have been happy if I had missed my connection. And missed valuable bonding time with my son.
