I recently used vistara airlines to travel from Delhi to Mumbai, from flight vistara uk 993 and it costed me around 4300 indian rupees, the flight was for about 2hours and I traveled from economy class.
I have to appreciate the service provided by them as it was full value for money.Baggage allowance was 15kgs for both adult and child.They also provide with in flight meals which taste amazing.
The check on and reception on board was also very good , the staff wad ready to help and very caring to serve the passengers.
I fully feel satisfied with them and would also travel with them in future.
Bon voyage.
