Peak-trips
For the newhires experiencing your first peak.
Trips tend to be like a roach motel, don't pick one up thinking you'll be able to modify your schedule easily.
R day drops - if they happen at all, timing will likely be a day prior. EG-during the 0700-0900 sick call lottery the day prior to your reserve show
I'd expect at least one Ops Emergency, maybe 2.
Potential for SUB due to limited aircraft ability much higher, so try and figure out your options now.
Things that I think will be better. If you're lucky enough to have trips, same footprint trades will be approved for the first time ever (if you win the time stamp lottery)
If you're a domestic hub turner, CRS will have to effectively pay you Draft to modify your layover city. (Peak 2014 people bid their home cities only to show up in Memphis and have their trip revised to operate elsewhere. Rather than doing that this year, CRS has been cancelling the trip and assigning a SUB trip)
On cold days in Memphis, expect long, long delays as our support folks decide whether to come to work when the weather sucks. (Unfortunately the same is especially true of our deice trucks)
Good luck, keep your sense of humor, and wear a Christmas tie.
Personally, I tend to think that if the companies going to create a whole slew of additional Airport Stby's (some of which will go unfilled) it's Christmas tie season
