With Kuwait threatening to disallow landing of India's state-owned carriers at its capital from Sunday, passengers planning to fly to India during summer holidays are now pinning hopes on the crucial talks between both countries.

While civil aviation authorities of both the countries are engaged in a second round of negotiations in New Delhi, the Indian Ambassador in Kuwait and civil aviation ministry joint secretary are expected to hold parleys with their counterparts before July one in Kuwait.

"If the flights between the two countries are halted, the services of India's national carriers, Air India and Indian to Kuwait will be heavily disrupted," Kuwait Times report said.

"Passengers who have bookings with the two airlines are calling us and want to know whether the said airlines have taken into account the worst case scenario," one agent was quoted as saying in the Arab Times.

Despite the uncertainty, travel agents said they were undertaking bookings of Air India and Indian.

"We will continue to do the bookings unless we receive any message from the Indian national carriers to stop the bookings."

The crisis for passengers between India and Kuwait was aggravated after the latter issued a notice to Air India and Indian saying it will not receive flights of the airlines from July 1.
