Seat Guru - www.seatguru.com

The site gives information about each seat and gives you the ability to avoid seats that has a problem - such as near lavatory, tv screen on bad location, no power socket etc. The "art" of choosing a flight seat is more than only window or aisle...

It helped me many times, especially on long flights.

In case that there is a limited time to choose your seat, my advice is check the flight details in advance and be sure about the model of the aircraft since each model has it own problematic and better seats.

Thanks a lot SeatGuru.
