well, on a recent overnite, van scheduled at 5pm, comair crew is in the lobby at 10 to 5, just like me, waiting on FA and CA. to make a long story short, they took off without us at 4:55 pm. they did see me, they knew we needed to go to the apt as well...did i say their plane was late too! we pushed out of the gate while their bird just pulled in. i can't say i was very pleased about that. at least we were able to still make an on time departure.
