Flew them from MSP to Chicago because they were cheaper than NWA. NEVER again. We had a 7am flight - usually the ones with no delays - so we had been there since 5:30-ish and they didn't tell us until 6:35am that the crew wouldn't be coming in because they hadn't had a enough sleep. Now, if this crew came in late the night before, they should have known about when we checked in and told us that there may be a delay because of that. Needless to say, our flight didn't depart until 9:30am.
On the return flight, we had another delay again, this time becausethe incoming flight was delayed from earlier inthe day. Talked with a guy waiting with me who said he is only flying Vanguard because he had 12 free tix with them because of a delay. He said they are always late no matter where you fly with them.
I am a very organized person and I don't like anyone dickering with my schedule so I will not fly Vanguard anytime in the future. Their cheap prices aren't worth their lack of punctuality in my opinion
