The Tata group airline announced a three-phase expansion of fuel surcharges across its domestic and international flights, including those operated by Air India Express, driven by surging aviation turbine fuel (ATF) prices due to supply disruptions in the Gulf region. In the first phase (new bookings from March 12), fuel surcharge for domestic and SAARC flights has been revised to Rs 399. Previously, there was no fuel surcharge on domestic flights and flights to and from the SAARC region. Similarly, in the West Asia/Middle East region, where there was no fuel surcharge, the same is revised to $10. In Southeast Asia, the fuel surcharge has been revised to $60 (up $20 from $40 and it also applies to Singapore from this phase).
