Air India 787-9 Dreamliner

Yes. Business is a one-two-one cabin where every seat reclines to a flat bed and has direct aisle access, so nobody climbs over a neighbour. It is a modern long-haul product carried on the ex-Vistara aircraft.

Yes. In the one-two-one cabin the single seats on each side suit solo travellers who want privacy and their own aisle, while the two centre seats suit people flying together. Every seat is lie-flat with aisle access, so the choice is about position.

The bulkhead rows just behind a forward cabin give extra legroom, and Premium Economy is the value pick for more room without a Business fare. The rows near the rear galleys and lavatories are best avoided, where the queues and clatter collect.

For the seat itself, yes in a good way: this is the cabin Vistara fitted before the merger, so the finish and the three-class layout feel a cut above Air India's older inherited jets. Frequent flyers still talk about which tails fly which route, so the seat map for your flight is the thing to trust over the tail history.
