I like what I hear about ATP. The swaying vote is the amount of Multi-time in their program.
The other warning to your student is preparation - every mill school (Comair - PS now Called DAA or Delta, Pan Am, FSI, North American, ATP) wants your money. Their guarantee ends where you have the capacity to stay within their 141 approved curriculum. If you are not prepared and ahead of every course, you are going to be throwing quite a few extra dollars into this scheme. Because anything which is a remedial lesson or re-check is extra cash and when you see their rental rates outside of the curriculum - WOW!
