According to the current LBA CEO, his predecessor, the one before that, and the one before that, they very much do matter. They've all indicated that premium flag carriers such as Lufthansa, Air France, Iberia , Turkish etc. demand a certain level of experience for their passengers . It's been said that LBA had little chance of attracting them unless and until the terminals obvious deficiencies were rectified. Now, that's happening.
By 2025, the arrivals experience, by far LBAs weakest link, will be first class. The following year, the entire terminal will be vastly improved.
LBA has the catchment area without doubt. The problem is convincing airlines that this side of the Pennines is not just another part of MANs catchment area and one that can stand alone. Obviously LPL were able to convince Lufthansa they were something more than the MAN catchment area so there's no reason why LBA can't do likewise when the terminal upgrade is completed, which should
co-incide with Lufthansa's fleet availability returning to normal and the opening of a rail link via the new Parkway Station.
