AFAIK:
- Wizz have no aircraft based at Luton
- Wizz have no aircraft based at Tallinn
- Wizz have no routes to Tallinn
Any routes from Luton to non-Wizz bases need to operate a W:
Base - Luton - Non-base
-OR-
Base - Non-base - Luton
To add a Luton - Tallinn route this can mean:
- A Base - Luton route needs an increased frequency to then W and do Base - Luton - Non-base
- A Base - Luton route which currently does not W needs to start to W (big impact on schedule)
- Wizz need to launch a Base - Tallinn route which will W to Luton (that's wishing for a lot...)
