Is it JetLite (9W’s orginal LCC) or JetKonnect (Air Sahara)? Either ways I think both those companies exist for business reasons - aircraft ownership/lease and other complicated things.
9W has retired the brands though after the debacle of trying to explain to customers why they were getting the LCC treatment despite having got tickets for “Jet”. It was comical. I don’t know whose idea it was but it was over 3000 kinds of dumb.
Since all that has passed they have fitted all the S2 and aircraft with standard jet seats 8J and remaining Y on typical A320/B737 types. I don’t think they’ve done the sneaky thing AI has done with the European J type of seating on some of their aircraft.
I think you’re being informed it’s a JetKonnect flight because that company technically owns/leases the aircraft but it’s going to be in a standard JetAirways hard and soft product.
