If you're an airline pilot, then you've already flown with some awful people...they also went through the interview. If you're not with an airline yet, you, sooner or later, WILL fly with those awful people...who have cleared interview at one time or the other.

What do you think of 'flow-through'? Just remember that those who 'flow-through' never went through 'that' airlines' interview process. In fact, I know at least five guys/girls who were rejected by AA and Delta (two of them twice), who are now flowing through to same airlines.
