Luton - Varna appears unbookable from the end of March.
How do Wizz operate the Kiev and Riga services? The aircraft go out from Luton at 13:00 and 14:05 respectively, and return at 20:05 and 20:10 on alternate days. However, there is nothing back to a base at 20:35 or later. Are aircraft nightstopping at Luton?
Some Sofia services have been retimed, as the same aircraft does Luton - Bourgas and Luton - Zagreb.
