AIBU to think that there should be an app that if you add departure station and arrival station and state an open date or perhaps a date range that you can get the lowest price tickets displayed? Background is that I need to start visiting my elderly parents more often and support my siblings. I don't need the car when there, it's a 4 hour drive, I work from home and can work on the train. I can travel anytime on any date. I'm just trying to maximise my contact time for the cheapest outlay. I may as well work on the train and have quality time with parents. Any ideas anyone?
