Comment Disney World, anyone? (Score 1) 279
Disney has been using this stuff for a similar purpose for the past three years and they keep the information much longer than Heathrow's 24 hours (Disney officials state that the info is retained for as much as 30 days after the last use or expiration of a WDW ticket - your fingers aren't broken, I know you can do your own Google search to verify it). I guess if it speeds things up, and heaven only knows that Heathrow needs help in that area, then I have no problems with it.
