I would expect LY to close the LHR lounge, it's too old, little, ugly and it has no toilets. They only have 11 weekly LHR flight, doesn't the cost of renting LHR space for only 11 weekly flights is too high?
They can use the bmi lounge or the *A lounge which are much better, and pay less. It's a win-win situation - both for them and for the customers.
