I signed up for email alerts with Trainline for when cheaper tickets come on sale for a return trip to London in July. Got an email yesterday about the outbound journey, so snapped up 2 tickets for £44, and expected there'd be one about the return today. But nope, they're still £120 - 250 However, if had booked them yesterday, still as singles, they'd have been cheaper. How can inbound singles be cheaper if you book them with outbound singles? Now I've signed up for another alert for the inbound tickets, and they say they normally release the cheap tickets 12 weeks before travel - so how come I was able to buy the others yesterday? I fucking hate this system.
