Last week, all of the airline rewards (except American Airlines), disappeared from my e-rewards account. I sent an e-mail to e-rewards, and they responded that customer's accounts had been "realigned" to reflect the sponsor from whom I received my original invitation.
But today, all of the airline rewards re-appeared in my account...... more airline options than I had ever seen before (approximately 10 airlines, including Alaska, Delta, USAir, Iberia, etc.).
I am not complaining, mind you. I immediately redeemed as many Iberia Avios as I could.....
