Vistara is a domestic airline. I travel many time from this airline. and I never face any problem in check in or check out.
most important thing is its budget buy for everyone who travel frequently. the food is ok ok not so good and options are only 2 for economy class. and the attendants are well dressed, well mannered, and soft spoken. they know their duty very well.Punctuality is their priority.And comfort of the seat and all was very nice.
