Indian airline carrier Vistara has announced that there will be no uniforms for cabin crew owing to supply problems and an increase in staff.

"Vistara is experiencing limited availability of its cabin crew uniforms," the carrier, a joint venture between Tata Sons Pvt Ltd. and Singapore Airlines Ltd., said on its Twitter account in a post titled "Important Update."

It cited an "unforeseen issue" with the supply of material.

Some cabin crew will have to wear black trousers and polo t-shirts with the Vistara logo instead of the standard aubergine-colored tunics, the statement said, describing it as "not an ideal measure."

With travel demand rebounding rapidly after the pandemic, the global aviation industry has struggled with an array of shortages, from new aircraft and engines to flight crew and baggage handlers.

Vistara, which is in the process of being merged with Air India Ltd., said it was actively working with suppliers to resolve the issue and its focus remained on "delivering world-class customer service."
