Vistara A321 or 787 Dreamliner routes?

[Dragon_slayer]

Hello everyone, I would like to know which domestic routes Vistara flies, 787 or A321? Also, are there any other Vistata domestic flights with the business class of 1:2:1 configuration? Looking to book business class tickets on these flights only
