DTW at SkyWest would be easy to get out of training. Reawrves have two hours to get to the airport, I'm not sure how long it takes to get from the parking lot to the gate, so can't help you there. Upgrades are around a year and a half or so, crews in DTW are great and the trips are ok. Chicago has better flying, but if you live in DTW, nothing beats driving to work. Good luck!
