The lack of responses from FlyerTalk staff might indicate that they don't know what's wrong. I've noticed that the slowness problem clears up early in the a.m. which might indicate reboots of the server.
I've done tracerts and there doesn't appear to be a network-related problem. It's either the app or the server.
Why FlyerTalk staff fail to let us know is both frustrating and unprofessional. We aren't here to browbeat this but a little courtesy and information would be nice. We are the customer and can be understanding with a little bit of feedback.
