Looking at RDU-LHR for a few dates this year I see these "Economy Web Specials" all over the place now. For a random date in June the sAAver price is 30k, but depending on the flight selected the Economy Web Special prices as 28k/29k/31k/32.5k/33k/37k/39k/40k etc. etc.
Better than 110k AAnytime but you can see exactly where this is headed, variable award pricing here we come. Interestingly they all carry a booking code 'Y' just like AAnytime.
The good news is that for a number of dates I was looking at in June for example the Economy Web Special had options for 20-25k which is a good savings over the usual 30k for sAAver. And since it books into Y they are essentially not capacity controlled a la AAnytime space (as long as Y is available, at least it seems at the moment).
Mods should probably adjust the thread title as this is definitely not just for sub-500 mile routes anymore.
