High fuel prices and increased aircraft acquisition costs may lead to a delay in IndiGo’s plans to launch low-cost, long-haul direct flights to Europe, reported Business Standard.

The airline is mulling to acquire A321LR, which will help to operate flights to European cities in nine-hour range in place of Airbus A330neo wide-body jets that it had planned to buy earlier, the report said citing multiple unidentified people aware of the plan.

The development comes after worries merged within the company regarding the profitability of the plan, according to the report.

The carrier, instead will focus more on increasing its operations in West Asia, Southeast Asia and China, the report said.
