Do not, I repeat, do not do any prep. This has been covered in this thread. It's a huge pet peeve of the ground instructors. The Airbus is extremely easy to learn and Frontier flies it differently than any of the other guys. The guys at the school house are constantly complaining about having to re-teach new hires the "Frontier" way of doing things. Doing an Airbus prep is a waste of your time and money. We have a great training program. You will get through and there's no reason to make it harder on yourself but trying to get too far ahead.
