I think adding more Indian airline liveries would greatly improve realism and variety in the simulator!
For Air India, it would be great to see the A319-100, A320-200, A321-200, 787-9 (new livery), and 777-300ER included. Updating the Vistara livery with the “Operated by Air India” marking, similar to the 787-9, would also reflect the current fleet accurately. In addition, the older A320neo livery seen on aircraft such as VT-RTZ, VT-RTV, VT-RTM, VT-RTL, VT-RTX, and VT-RTU would be a valuable addition.
Air India Express would also be a strong addition. Even though the livery design is detailed, it is achievable. Adding at least two liveries for the 737-800 and the existing A320neo variants would improve representation, especially until the 737 MAX 8 is introduced
Since the SpiceJet livery is already available on the 737-900, including it on the 737-800 as well would make the fleet feel more consistent.
Finally, adding the Kingfisher Airlines livery for the A320-200 and A321-200 would be a nice tribute to an airline that played an important role in Indian aviation.
Overall, these additions would enhance variety, realism, and the overall experience.
