Let's be honest, it's a faff. Even with a couple of recent apps, getting a refund often requires a pigheaded determination to screw TfL for every last penny in recompense for suffering incurred. But these are straightened times, so a new website might come in very handy. mytubewaslate.com only asks you to fill in your details once and tell it which journeys you make most often, so it can email you when a refund-worthy delay occurs. Or you can search for delays and be reminded that way. You still need to claim within 14 days but it takes a lot of the hassle out of getting that £2.70 back. It might not sound a lot, but we once got so hacked off with the Northern Line we claimed £20 in a month - that's a fair bit off your next travelcard.
