Updated: March 5 2025 | Tagged: United Kingdom, Travel Hacks
In this post, I show you how to travel from Milton Keynes to London Heathrow for just £9, making use of the bus fare cap scheme where you can travel on selected routes in England for just £3 per ride (£3 national bus fare cap).
The journey from Milton Keynes to Heathrow is done in 3 stages:
The same journey with the train would be a minimum of £16 to Euston if you are lucky then a minimum of £5.60 on the Tube depending on the day and time.
This is a big saving.
Of course, it's gonna take a while to use the 3 buses and Arriva doesn't run from MK to Aylesbury on a Sunday so take that into consideration. Always check locally for schedules and changes.
And depending on your terminal, you might have to take a free Heathrow transfer from the Heathrow Bus Terminal to your terminal.
