The Flighys must warn you as quickly as possible if your flight is canceled or delayed; this is usually done through airport announcements, emails, or texts. The airline will usually rebook you on the following flight to your destination at no additional cost. Additionally, you can ask for a rebooking online, at the ticket counter, or by contacting customer care. Depending on what caused the delay or cancellation, different compensation policies apply. Under some rules, like EC 261/2004 in the EU, you can be entitled to compensation for problems that are under the airline’s control, such maintenance or staffing issues. Although it isn’t required by law, several airlines in the US provide assistance as part of their customer service guidelines.
