As part of the campaign, guests travelling from Gatwick can secure their flights from £1 when heading to Symphony of the Seas in Barcelona or Odyssey of the Seas in Rome next summer.
The line is also offering £150 savings on airfares from select UK airports for European sailings departing between 16 April 2023 and 22 October 2023 on Explorer of the Seas, Rhapsody of the Seas, Symphony of the Seas and Odyssey of the Seas.
Meanwhile, guests who book an Oceanview stateroom on any Anthem of the Seas’ European itineraries sailing from 12 May to 3 October 2023 will be upgraded to a Balcony stateroom.
Guests can lock in their holiday with reduced deposits from £99 and the line’s drinks packages are available for £43 per person, per day on seven-night or longer sailings onboard Anthem, Odyssey, Symphony or Wonder of the Seas.
Stuart Byron, director of sales UK, Ireland and Spain Royal Caribbean International, said: "We’ve listened to both our customers and guests and have come up with a bumper Mini Wave offer.
"We know that flight challenges have been a key consideration for many this summer, so by providing more plane seats for our guests than ever before, we hope to give added peace of mind for summer 2023."
