Respectfully disagree...I would go EMJ for sure.

First of all, uless he plans on staying on the ATR (most want to transfer after the 1 year seat lock due to the significant pay differences), he would be going through two long term training cycles in Dallas of approximately 4 months total out of 14 months. Assuming he gets awared the EMJ right away.

Second, I heard that the commute from Orlando to Miami is rather difficult. I know a lot of captains that commute to Chicago out of Orlando instead of Miami because of the larger planes and many more options.
-just what i've heard on the line

Third, I think the schedules and trip trading option once you are able to hold a line are much better on the EMJ. Although, I will admit, you probably will hold a line much sooner on the ATR.

Finally, you have the option of transferring to any base except SJU if you were to decide to move at a later date.

Just my thoughts...
