Vueling is adapting to the exceptional situation we're all facing by offering several flexilibility options for your current and future bookings.
We also recommend that you check our communications regularly for updates on changes in our operations. More information on Vueling News.
We understand that these exceptional circumstances are causing uncertainty and impacting your travel plans. On this page you’ll find updates on the disruptions due to Covid-19 and the options available to manage your bookings.
Please check your inbox regularly in case you have received an email from Vueling. We are gradually sending out notifications about the following:
Flights disrupted due to changes or cancellation
Options available for flights that haven’t been cancelled
If you have received any of these notifications, remember that it’s easier to manage your booking through our digital channels (web and app). The options available through these channels are exactly the same as those available through our customer service call centre."
I recommend you log on in in English and follow "Manage booking"
FYI there may be a travel ban that prevents you from landing in Spain. Border closed till April 22.
Spain is not managing Coronavirus well.
