Private sector carrier Air Sahara will commence its daily service to Britain from the last week of October and has secured landing slots at London's Heathrow airport for all seven days, company officials said.

"We were earlier disappointed that we could get permission for only two days a week to fly the New Delhi-London sector," a senior official of the airline said.

"We have now secured slots for all seven days a week at the Heathrow airport in London. Our Delhi-London service will start from the last week of October," the Air Sahara official told.

To start the service, the private air carrier has leased two Boeing 777-200 Extended Range aircraft of 2001 vintage from the International Leasing and Finance Corporation (ILFC), both fitted with General Electric engines.

"The two aircraft will go for the mandatory 'C' and 'D' checks overseas," the official said.

"The carrier will hire six sets of pilots and crew to operate the aircraft. They will be both expatriates and Indians," the official added.

According to Air Sahara officials, the additional frequency was made available to the carrier after a new bilateral air services pact signed between India and Britain in April this year.

Under the pact, it was agreed to increase the total number of flights between the two countries from the present 40 to 130 per week.

Indian carriers have the leeway to operate 56 flights from Delhi and Mumbai to London's Heathrow airport and also have unlimited flights from India to Britain on all other routes.

British carriers can operate 56 flights a week from London to New Delhi and Mumbai, 14 flights a week to Chennai and Bangalore and seven flights a week to other international airports in India.
