Manchester will do well for @IndiGo6E  if this happens. 

Let's see which London Airport they select. I hope they launch at least one daily flight to London Heathrow from Delhi. However, I think they will go for London Gatwick.

The timings, if correct, indicate that Indigo is planning to target transit passengers on this flight.

Also, if Indigo launches, will Air India strike back and bring forward their Mumbai (BOM)-Manchester (MAN) plans?
