Colgan is what it is, it is not right for everyone but it is perfect for some.
Just do what you are doing, do you research, look into all of your options and make the decision that works best for you.
If you can get in and get hired into the Q on Friday you may get the next class which will put your seniority in the top 20% or so for that plane and seeing how you want to be in the EWR LGA area it may be a good fit for you and have some good growth potential. There have been alot of talks about getting more bombardiers on the line and I am nearly positive that the fleet will not stop at the initial 15 by june. There are already 4 total bases for the 400 with a few more in the works in the not so distant future as well.
Let me know if you have any questions.
