The airline has painted an Airbus A320 with the colours of the contest and a retro musical note design to mark the occasion.
The aircraft can be spotted until the end of the summer. Until then, Vueling will offer a special Eurovision on-board menu called “12 points" - the highest score that can be awarded to a country during the voting process.
This will bring together different dishes and drinks from participating countries.
The interior of the Airbus will also be decorated to host an in-flight event on 12 May, two days before the final. Vueling said “many surprises” will be revealed.
