If you don't already have a code, you've missed your chance, sorry! We stopped accepting submissions for Plane Relief promotional codes at 23.59 on 3 November 2016.
That was in the terms and conditions so the offer is no longer available.
I'm positive it's only £30 one way and that's only on offer on certain days/times.

Cheers. Just looking at the stadium plan on the SFA website it seems to suggest that some of the home fans will be in sections 534-539 which is above us in 129-133?
