However, LH requires only 17.5 percent of the slots in LHR. They certainly have no intention to keep all of the regional flights in the UK BA is required to offer because they only have one hub. I would assume (just by a judgement of the thumb) that the London region covers 80% of the profitable market in the UK. What I can imagine LH to do, is using the London slots for profitable long and medium range flights, forget about quite a bit of the regional network but direct the customers from the UK regions into FRA or DUS for connections. LHR-DUB will certainly survive but I am not sure about the rest.
