The proprietary font is named 'Easyjet' (surprise!). It comes in both rounded and plain extended families. The family includes at least Book, Light, Demi, Bold, and Headline variants, as well as matching italics. In some instances the font is simply named EJ.

Thank you! But where did you get those PDFs? I can't find any in the site.

EJ Rounded Headline, their corporate typeface for headlines.

i find that if you google the company name + pdf you can usually find an annual report, and sometimes more.
