I had traveled on Vistara from delhi to hyderabad international air port, I had a good experence in vistara.
While checkin they recieved me with high manered and respectively, they them selves took care about my laugage and packed it safe to bagage, they also asked me to selecte the siting position which is avalable at that time.
after entring to airbus I have nice experenced nice ambeience , the leging space is also very good, the food provided by them is very higenic and taste and its a complementry to all custmers.
my first preference will be vistara for traviling in air.
