Gotta say, I am very happy with my Gold subscription to MyFlights. LHR - TLV swapped from a 787 to 777 and got the alert. Sad, no Dreamliner, but thought I would check F availability (it was an Avios 2-4-1 redemption in Club). Sure, enough there were two seats outbound and inbound, so on the phone to BA! EF gave me the alert about 6 hours later of the F availability.
