Just so you are aware, your previous experience has no bearing on what aircraft you would potentially be assigned to as a newhire here. Your seniority in class will be determined by the last 4 of your SSN (9999 is high 0000 is low). The aircraft available to your newhire class and your seniority within it will be the sole variables there. This is a big difference from the way it is done at many carriers in other countries. Same story at American and United.
