Welcome,
ExpertFlyer Voice! It feels good to this FTer to have somenoe who is involved with EF here... at least lurking regularly, and at best, helping sort out common concerns or quesitons. Some of us will also be able to direct others, as we learn to use the system ourselves.
It will be great to be able to read PNRs from other GDSs, and to expand the number of airlines we can check for award or upgrade seats on. But so far, I have to admit I have used EF to find several flights worth of seats for I-class fares, upgrades using VIPs, and finding the "impossible" to bring some Aussie friends over the big pond in J on AA miles. (If the AAgents knew how I got the information that saved them so much search time, they'd probably want to thank you too... unless they made a nasty comment in my PNR!

)
Speaking of which, the Fare Class tables are a good start, but the fare classes vary so much I had to guess for that 'roo line's J cabin award seats. So we'll be happy when "U" get that sorted out as well... Those of us in the EF user community are looking forward to all the developments you mention, and I at least feel it's a great match to have the data available from EF and the personal input and experiences from FT. ^
(No, not shilling - I like to give feedback, both positive and negative, when they are due.)
