I just got an email from ExpertFlyer asking if I might be interested in joining a Beta program to test and provide feedback on new features. I gather there are a few on here who also use EF so will be interesting to see what these are. I'm sure a few here also received the same email.
The email suggests:
What's in it for you:
Be among the first to test new flight search and alert capabilities
Direct access to our development team
Shape the features that matter most to you
Your participation would require about 1-2 hours per week during the months of April and May testing new features and providing feedback.
Who knows, maybe one of the new features will be R class visibility

(I'm 99.9% sure this is determined by NZ and not EF).
I'm generally pretty happy with the value I get from my EF subscription and will be interesting to see what kinds if features they are adding.
