Most runs are Monday night Through Friday morning. There are some runs that run during Saturday as well. People are placed in bases as needed. There are more pilots then there is flying. If your looking to fly a bunch, it will be difficult now. There are at least 7 people waiting to start training and there are 5 check airman. Most runs are short. Only about 5 runs that are long. You are not guaranteed holidays off. You may spend your holiday at an out station away from your home. If you float, you will most likely get home on Friday night and then have travel Sunday. Last time I looked pretty much all bases are full with people having standing bids for when others leave. Seniority is factored within the base. You may be a DE Captain but once an FO upgrades in base, if he is there before you, he will then be senior to you. On one happy note, you get a week off every month. Hope this helps.
