I have had a nice experience avery time I have flown Air Deccan. I was working in Hyderabad for approximately 3 years and I had always dreamed of something like a "weekend fare" concept. It finally got true and I was able to fly very often to Delhi on Air Deccan to meet my family all this time. Overall, its not a bad experience for a 4000 bucks retuen fare booked at the last minute and close to 2500 return when booked in advance.
I will recommend this to all people who are frequent fliers on AD routes. Also try to avail their Katra Vaishnodevi services. I hope that they increase their flight frequencies and get more planes to their gleet and start a lot many routes to benefit most people who want to fly real "economy".
Ground Services = OK
Flight Attendants = Average
Plane Neatness and Seating = Just like any other economy class, remember they dont have blankets and pillows!
