Yep - I noticed this today, too. Years ago, they required you to enter your AE number to look-up flights - then they took the requirement away (not sure when...thinking about 2-3 years ago?) and now they've added it back. Wondering why? Probably so only those with the right amount of points can see scamcharges? Or are they just trying to make it as cumbersome as possible to view available flights so you just give up and call - or just look up merchandise instead? Ugh...
