Regardless of the time of day you decide to fly, the ticket price will remain around the same. Book flights from Cork to Basel as you normally would.
If you have been vaccinated, you can either show a Swiss COVID Certificate, EU Digital COVID Certificate, or a certificate that is compatible with the EU Digital Covid Certificate.
Travelers who have been vaccinated abroad with a vaccine approved by the European Medicines Agency (EMA) and who are resident in or traveling to Switzerland are able to obtain a Swiss COVID certificate. This means that travelers who have been vaccinated abroad or have recovered abroad, such as tourists, can also participate in social activities in Switzerland. The documents can be submitted electronically. Currently, only the certificates of countries using the EU Digital COVID Certificate are compatible with the Swiss system.
You will be issued with the COVID certificate on the application on paper or as a PDF document with a QR code. With the COVID Certificate app, you can host your COVID certificate on your mobile device.
If you are unvaccinated, you must have a test, and if the result is negative you can then be issued with a COVID certificate.
