Civil Aviation Minister Jyotiraditya Scindia on Wednesday said existing fare caps act as a protector for air travellers as well as airlines and indicated that doing away with the curbs could be looked at once the environment stabilises in terms of passenger traffic and jet fuel prices.

However, jet fuel prices are at a high level and many states have reduced the taxes levied on the fuel.
