There are a whole can of worms to consider over these proposals.
A two terminal solution is also going to be a far more expensive option regarding running cost when its competitor (Stansted) just keeps increasing the size of its single terminal so keeping costs down. Two lots of everything planned at Luton including security staff and separate terminal infrastructure to be maintained.
Phase 2a claims to be for a new terminal with a capacity of 5 million passengers. Assuming Luton's 3 major carriers remain and don't go bust it is already too small to handle all of Wizz's or Easyjet's traffic leaving them in a congested Terminal 1 unless they have a split terminal operation. This would leave Ryanair and any small carrier heading for T2 but then T2 is further away from the A roads and M1 on a shocking road network
The access road for Terminal 2, that is mean to be finished by now, is unaffordable, as it was the Council who was going to fund it. Now under Phase 2a proposals it will now only be part built with a massive gap in the middle leaving traffic battling along Percival Way, which is the road that hugs the hangar line. It's a dogs dinner solution. It gets worse even when T2 is expanded to 32m , as traffic to and from the A1M and heading for Terminal 2 will still be expected to use minor roads on a housing estate to get to the airport. It will be worse than Southend. This missing link though will be put in sometime after 2032.
Artist impression shows a swanky new terminal but this is a section of the proposed approach road from the M1 that will not be upgraded and is part of the missing link
