Dec 6 (Reuters) - India's Ministry of Civil Aviation

said on Saturday a directive has been issued to all airlines

mandating strict adherence to all fare caps that have been

prescribed to protect passengers from any form of opportunistic

pricing.

The price caps will remain in force until India's flight

situation fully stabilises, the ministry said in a statement.

Air travel across India has been in turmoil this week after

IndiGo cancelled thousands of flights, prompting the

government to announce special relief for the carrier and the

operation of additional trains to help clear the backlog.
