Ryanair is adding more than 20,000 seats to Portugal from Scotland.
Extra flights will be available for the summer from May 24 after Scotland followed England in allowing travel overseas to 12 green list destinations, including Portugal.
Ryanair is boosting capacity from Edinburgh to Faro, Lisbon and Porto, and from Aberdeen and Prestwick to Faro.
Fares for travel until the end of October are available at £19.99 in a flash sale running until midnight tomorrow (Thursday).
The no-frills carrier’s marketing director Dara Brady said: “We are very pleased to announce these 20,000 extra seats to Portugal on the back of Scotland’s green list.
“With quarantine-free travel now permitted to the likes of the Algarve, Lisbon and Porto, these additional flights have been added to our Scotland schedule in order to meet the demand from our customers.
“Scottish families can now book a well-earned summer holiday safe in the knowledge that if their plans change, they can move their travel dates up to two times with a zero-change fee up until the end of October 2021.”
The move came despite Airlines UK, Glasgow and Aberdeen airports owner AGS Airports and Edinburgh airport describing the Scottish government’s announcement on restarting international travel as a “missed opportunity”.
A joint statement said: “Whilst removing the travel ban is a step in the right direction it is very much a missed opportunity with so few countries making it onto the green list.
“We are again in the position of being a week away from a major change to operations and are waiting on details of how the Scottish government wants this to work and how it will be managed. We need that detail as soon as possible to allow everyone to understand what is required.
“We appreciate there are many things to consider but we encourage the Scottish government to work with us on making testing more affordable rather than it being a barrier for those who need and want to travel.
“We would also encourage government to take advantage of the vaccination rollout to open up many more green countries in the EU at the new review point in three weeks, as the EU themselves have proposed, and to work where possible as the four nations to ensure consistency and avoid confusion for operators and passengers.
“The Scottish government must also be very clear about when and how we can encourage visitors from green list countries to try and save the thousands of jobs in Scotland that depend upon international travellers.”
