No-frills airline SpiceJet, which is trying to keep afloat amid several aircraft of its fleet being grounded over payment issues with lessors, on Friday said it plans to add 10 narrow-body Boeing aircraft, including five B737 Max, on lease by October. In the intervening period, the airline is working on restoring and reviving its grounded aircraft which will start returning back to service soon, SpiceJet said in a statement.
