To determine if your EasyJet flight might be cancelled, the most reliable method is to monitor the EasyJet "Flight Tracker" on their mobile app or website. This tool provides real-time updates directly from the airline's operations center. You should also check the email address used for the booking, as EasyJet is legally required to notify you of cancellations as soon as they are confirmed. If you see your flight "disappear" from the online check-in portal, this is often an early warning sign of a schedule change or cancellation. Additionally, keep an eye on the "Flight Information" boards of your departure airport's website. If there is a widespread strike, severe weather event, or technical failure at a major hub (like London Gatwick), the probability of cancellation increases. If your flight is cancelled, EasyJet will usually provide a link to rebook on a different flight or claim a full refund. Under UK261 regulations, if the cancellation occurs with less than 14 days' notice and is within the airline's control, you may also be entitled to cash compensation.
