I was at IFL for one day which was a great experience. The office personnel booked the ticket, hotel, had paperwork work ready, taxi from the airport was arranged and hotel was right by the office. Very impressive, professional, and on the ball. I read the posts on this forum before going to IFL and was hesitant. I only left because I got an interview with a passenger airline which is preferential to me because of flight benefits and where all my experience has been. I also prefer 1 to 4 day trips because I have two young kids. The pay is quite good though and 2 wks on 2 off can't be beat.
The instructor was professional and thorough and the Chief Pilot was very welcoming and friendly. What prompted me to post this is that I was asked how my experience was. I also mentioned not to worry about 1 day of pay which she said "That's not right. They'll pay you". Not sure what the story is behind any bad posts but I believe I would take them with a grain of salt.
