> Don't get me started on airlines websites

You can't beat China Southern . They have the most dog shit website I've ever seen. The flight was fine but I gave up doing online check in after 3 attempts. Never mind the bloat:

- required text fields with wrong or missing labels. One field was labeled "ticket no.". It kept getting rejected. I randomly tried passport number instead. It worked.

- sometimes fields only have a placeholder that you can't fully read because the field has not enough width ("Please enter the correct...") and the placeholder disappears once you start typing.

- date picker is randomly in Chinese

- makes you go through multi step seat selection process only to tell you at the end that seat selection is not possible anymore.

- signed up with email; logged out and went back to the SAME login page; now sign up via phone number is required!?

Almost nobody uses websites in China. You're expected to interact with them via WeChat Mini-app where the experience is generally fine.
