Reply To: Check Seat Availability before bookingBack to Forum
Yes there is, with http://www.expertflyer.com
You can check the fare availability and many other things such as the seat plan,. Be aware that this is not 100% accurate although i think it is the most you can get, also when you will check for a seat plan, this will show to you the seats which are blocked by BA as in some flights the first two rows are blocked until 3 days before departure, also on the European flights the first economy rows are blocked (from row 6 to 9 usually) until they know how long the club Europe cabin will be.
