The lenders of grounded Indian airline, Go First, have pushed back the timeline for submission of Expressions of Interest (EoI) by one month to September 8 due to a lack of clarity surrounding the airline's use of aircraft, without which the expert in charge of the resolution process said it will be difficult to find serious buyers. The airline has been grounded since May following the Wadia group's bankruptcy filing over sourcing delays from American engine maker Pratt & Whitney.
