If you have a plan of travelling in Swiss Airlines and booked the flight ticket, you reached the airport at the time of the flight departure but the flight is delayed.
Now you cannot do anything in order to make it on time.
The only thing you can do is to know how you can get compensated against the delay in the flight.
The airlines always try to stick with the timing they informed to its passengers but sometimes it is not under the control of Airlines (bad weather, air traffic etc.)
In case of a flight delay, the Airlines offers you a voucher to make your ride smoother but wait, accepting this kind of service will lose the chance of getting Swiss Airline's flight delay compensation.
You can check whether you are eligible for the compensation or not by using your flight number, email address and name once you enter the details you will be able to check the status of getting the compensation.
