Sources and verification
Baggage, fare, check-in, disruption and contact figures are published only when they are read from Winair’s own pages or a named regulator, and each one shows the page and the date it was checked. Where sources disagree we show both and publish neither. Route and destination figures come from the Originfacts route dataset and show its date instead; they are not verified by hand.
