Gulf Air and Saudia aren't happy with Adani's plan to shrink Mumbai Airport's capacity and move some flights to Navi Mumbai, which is about 50km away.
They say this change could mess up their flight schedules and make it harder for people traveling for Hajj and Umrah, since Mumbai is a major starting point for these pilgrimages.
MIAL wants 5 million passenger cut
MIAL wants to cut five million passengers a year from April 2027 because of terminal upgrades.
This would affect about 15% of international flights, including those of 11 airlines from the Gulf and West Asia, plus Nepal Airlines.
Gulf Air has asked for more details on why this is happening, warning that if things don't get sorted out, they might take it up with aviation authorities in India, Bahrain, or Saudi Arabia, and even consider tougher steps if needed.
