If you choose to put hard restrictions on which airline you will and won't work for due to the desire not to commute (which in some ways is a valid reason) you must be willing to live with the consequences that that decision might have on your career growth and access to future opportunities.

ExpressJet, either fleet, is a proud airline staffed with some incredible people who work under a fantastic contract. Unfortunately, the undeniable truth is that this is also an airline that has been shrinking steadily at an alarming rate over the past 5 years to the point where in 2-3 years the possibility of it ceasing to exist entirely is very real. I would highly recommend considering another regional that has growth and/or a more stable future, but if you choose XJT, you'll enjoy the training and operation and should something positive happen you'll be in a great position to ride that wave up; worst case scenario you start over at another regional should XJT shut down.

Best of luck, do what is right for you and your family and your quality of life, but do know that the future of ExpressJet is in serious doubt.
