I searched the US DoT website for evidence of this. Found
nothing.
Link please!
Ryanairs claims of 85% punctuality are unfounded. What are their methods of calculating on-times?
Where is the independent statistic?
Likewise on passenger complaint rates?
Link please!
By the way, your other link takes us to a website called 'uk-airport-news.info'.
Checking the Whois registration it belongs to one Nick Bradshaw, who is also a registered owner of '1stholidaystore.co.uk' - a commercial website.
UK Airport Info also sells advertising.
So it is a commercial website, with a registered owner who is in commercial operations within the industry.
"And if you want to support us, please book your airport hotel and airport parking via our website sponsor".
Who would that be? Ryanair perchance??
Hardly objective or independent then, eh?
