Putting this out again :
I have flights booked Southend-Malaga-Southend, departing Weds 29 May, returning Monday 3 June. £306.
I've now baulked at/chickened out from staying over due to the accommodation costs in Madrid and am looking to sell on the flights, at face value. I'll cover the name change charge. Thinking it might be of interest to anyone who already has mates with a hotel room/air bnb they could use.
(Potentially train tickets Malaga-Madrid-Malaga, Fri 31st - Sun 2nd - approx. £116, as well but need to look into whether they are transferable).
