Indigo Airlines is a very popular airline which provides flights . Yet another comfortable, friendly and smooth IndiGo flight flying from Pune to Bangkok via Kolkata. A caveat: In a hundred international flights into Bangkok in the past two decades, for the first time ever in my experience, an airline(IndiGo) did not have Thai immigration forms. Anybody who has been through immigration at Suvarnbhumi expects a wait of up to one hour. So, to not have immigration forms on board a flight can develop into an even longer wait. Come on, IndiGo! Otherwise, as usual, a flawless IndiGo flight.
