I'm interviewing next week, hoping for a class date in November or December.

The recruiting team is staffed by 3 people and when they are busy the emails don't get answered immediately.

Be patient, but definitely email them. I submitted my airlineapps profile and got a phone call about 430 PM CST that day, right before they went home for the day. I got a phone call at 8 am CST the next day (6 am my time...).

Granted, I'm over 1500 and meet all the reqs. All I need is a ticket to MSP for training, a hat to never wear and directions to the burrito shack at LAX.
