Hi, I do have the return section of a ticket I bought Jan 11 to travel from Luton Aiport Parkway to Nottingham, having in mind a return back to Luton Airport withn a month, which is very unlikely now to happen.
It is off peak but you can travel any day you want till Feb 10. I could swap it for another unused Luton-Nottingham ticket valid til late February or for some cash.
