Accessibility
Basic rules:
- Clear, concise, and useful text
- Informative page titles
- Headings, subheadings, bullet lists (proper usage of HTML elements)
- Don't skip headline hierarchy (after h1 should follow h2 and so on)

Screen readers
1. Avoid prepositions before cities
This is because it can be very difficult to localize this into various languages and make it sound properly.
Yes
"Departure: Berlin"
No
"Departing from Berlin"
2. Don’t skip headline hierarchy
Screen readers take headline hierarchy into account when interpreting HTML. Skipping can lead to problematic interpretation. Note: an “H1” should only appear once per page.
Yes
"H1"
"H2"
"H3"
"H2"
"H3"
No
"H1"
"H3"
"H4"
"H3"
"H4"
3. Avoid using all-capitalized text
People with dyslexia have harder time reading and screen-readers may interpret this text as an acronym.
Yes
"Book this fantastic trip."
No
"Book this FANTASTIC trip."
