Congradulations on passing your AMEL... I'm down here in FLL got my MEI today. I Passed my 7hr oral Yesterday and the weather didn't hold out for the flying but hopefully I can get it in ASAP.
As for the other questions. ATP-DFW is BYFAR the best location to go. I've been to them all and nothing compaires to DFW. Just to give you a little insite. I'm here doing my CFIs with a guy who started the PPL in Janurary. I started my PPL April, I've caught and passed him. Bottom DFW gets you done, only if you're motivated. I have yet to meet anyone who has done it as fast as I have at DFW. Another example one guy I did my PPL with in DFW left and went to another location. The same day I got my Commercial ME he was getting his AMEL.
Again Congrats. See you back in DFW!!!
