Dear friends,


I have booked my flights from Delhi to guwhati and return for 24/12/2010 and 28/12/2010 by Air india under LTC80. I have taken encashment of EL for myself and my wife has also taken as she too is govt. employee. But now Air India has cancelled the return flight from Guwhati to Delhi and no other flight is available for next 10 days under Air India. Can I perform my return journey from guwhati to Delhi by Pvt. Airlines as I am availing LTC ALL India Block years 2006-09 alongwith my family?. Please advice with suitable authentication.
Thanks,

P.K.Kapil
