Yes.
Suspect there’s an opportunity for someone to step up on the NQY-LON market.
Eventually we will see a LHR connection if and when R3 is built, however the most likely candidate for LON capacity short term I think is likely to be SEN via the flybe franchise.
An outside chance would be via BA who have just gained a significant dollop of LGW slots and with short block times it could help to slot sit the slots.
