Spanish airlines, Iberia and Vueling, announced on Thursday that they would return some flights from Madrid and Barcelona to foreign destinations, including Dubrovnik and Split, from the 1st of July, after those flights were suspended due to the Covid-19 outbreak.

Since a state of emergency was declared in Spain on the 14th of March, Iberia has only operated foreign flights to London and Paris so that passengers can reach their destinations in an emergency. Tourist travel was banned, and border police checked the documents and certificates of those rare foreign passengers at airports.

But after the Spanish government announced on Monday that it would allow foreign tourists to arrive in the country from the 1st of July, Iberia and Vueling announced the gradual return of their flights.

In July, Iberia will open flights between Madrid and Dubrovnik, which will be one of its 15 foreign destinations. It will introduce an additional 28 destinations in Europe and North Africa in August.

"In order to restore customer confidence, we will not charge penalties for changing tickets purchased from today until the 30th of June, for flights until the 31st of December," Iberia said in a statement posted on its website on Thursday.

Iberia also had flights between Madrid and Zagreb and Zadar, but it is unknown at this time what will happen to them.

Iberia's business in July and August will be at 21 percent capacity compared to previously forecast this summer, and in the event of increased demand, capacity could increase to 35 percent.

Flights between Madrid and Split can be booked via Iberia's website from the 1st of July, and passengers will be transported by Vueling Airlines.

Iberia and Vueling, in fact, have a joint owner, the company International Airlines Group.

"We can confirm that we will gradually return flights from Barcelona to Dubrovnik and Split from July," said Vueling's spokesman Xabier Martinez Serrano.
