We were on a flight from LAS to CLT. Flight was delayed in Vegas and we were concerned about making our connection to RIC. We were told there were 7 passengers that were also going on to RIC. Myself and my gf are Chairman and Silver members and was told they would hold the flight. It made since because it's the last flight and there are no connecting flights for anyone going to RIC. I can understand if our flight was very late but we landed at 10:22PM and since it was the last flight out why not wait 10 or 15 mins for all 7 of us. In stead of wait they left 3 mins early! Please explain!
