Heathrow Airport
The flight was more than 14 hours from Singapore to London and and the flight path had to carefully navigate the Warzones following many different borders. I was able to sleep for almost 8 hours on the flight and the movies I had downloaded were more than sufficient for the last part across Austria, Germany and Netherlands.
The wait was about 30 minutes for baggage after walking the endless tunnels to the security checkpoint and baggage claim. From there it was more tunnels all the way to the Elizabeth line which would get me to the City. Unlike Singapore the public transit was much simpler allowing me to just use my Debit card to tap on and off. I got off the train at Tottenham Court road using the Monopoly board as a way to determine how far into the City I was.
