Flight Availability alone justifies the $99/year fee for me, so I’ll continue to pay as long as it works well (and provided there is no new better alternative).
Seat Maps — and, especially, the Aircraft Change alerts — is of course very useful, and I’m hoping they fix it.
As to Award Alerts, well, I simply don’t count on EF anymore. *A no longer supported, and other airlines simply stop working without notice. There are much user-friendlier tools out there now, too bad this means we have to pay additional subscriptions.
