I'm traveling from Barcelona back to India in August. The following are my flight details, as I'd planned this trip long back- I'd gone ahead and booked a non refundable ticket (which was the only one available then as per my requirement). Now I need to reschedule my return and advance my travel date. Can anyone help me figure out how to do this while incurring minimum loss?
