NEW DELHI — Star Alliance, a global network of airlines that caters to frequent international travelers, said Monday that Air India’s pending membership had been suspended.

The move throws into disarray a crucial part of the Indian government’s turnaround plan for Air India, which has been struggling as customers have turned to more efficiently run private airlines.

The company has a reputation for late flights and poor customer service, and it is hemorrhaging money. Many employees have not received their full paychecks in more than a month, and former and current pilots have complained in recent months that the company was not following internationally recognized safety norms.

The Center for Asia Pacific Aviation estimated that the company had lost $1.75 billion in the most recent business year, which ended March 31. Air India reported a loss of $1.25 billion for the previous business year.
