Found a price that changed? Something wrong? Tell me.
The fastest way to reach me is email:
I read everything. I’m one person, not a support team, so replies can take a while.
What’s most useful to send
- A price that has changed — a photo of the menu, fare screen or receipt, and the date. If it checks out, I update the article and credit you if you want.
- Something I got wrong — a link to the official source, if there is one.
- A question an article didn’t answer — it may become the next article.
