Any ideas why there are no Advance Single rail tickets available on any late May or June rail trips? I am able to see them/purchase for April and early/mid May, but can't after that. I don't know if they have all sold out or there are none available in June. Any ideas?
We are taking train from London to Bath, Bath to York, and York to Edinburgh in late June and early July with Family and using a Family Rail card. When I priced those trips using early May dates it was 100 pounds or so. Now using dates in June it is about 350 pounds and there are no advance singles (which is why price went up).
