Mod note: Discussion of closure is post 48 onward.
There's a new frequent flyer friendly search service out today called
MileWise.
Like AwardWallet, you can enter in your frequent flier program credentials and it will scan your programs.
MileWise then allows you to search for flights and compare the costs and benefits of each (based on how much the ticket costs, your status, class of service, etc.), and will recommend which flight to take based on total value including miles earned.
Currently it is free.
I played around with it and so far it looks promising. Not all airlines and programs are implemented yet, so it is not a replacement for AwardWallet. It also doesn't support searches for premium economy. But it could make some mileage tasks easier.
Wondering what other people think of it?
