AZ has 3 configs on their 767-300ER fleet. These are referred to in schedules as 767, 762 and 763. AFAIK, 762 is the code for an ex-Eurofly 767.
BOM is no longer a dedicated ex-Eurofly route as it was in the past. DEL appears to be becoming one from March.
In March, BOM will upgrade to an M11 and DEL will downgrade to a 767.

Magnifica Class on the ex-Eurofly 767s is atrocious, on the regular 767s is tolerable, on the ex-AC 767s is good, on the M11 is excellent and on the 777 is fantastic.
