Sun worshippers have found themselves squeezed into great crowds of people at Mallorca airport, raising tempers and making social distancing impossible.
Holidaymakers using the Balearic Island airport are expressing health concerns amid reports that it is still taking an hour to get through security checks with "congestion and crowds everywhere".
The airport has also had issues at its passport gates, with Brits getting stuck in lengthy queues in order to have their travel documents stamped due to post-Brexit requirements.
Although many coronavirus restrictions have been lifted in Spain, the government is still advising social distancing where possible and especially at transport hubs.

Fed-up tourists say this is impossible at Mallorca's Palma airport and they are feeling "very insecure" being so close to people when Covid is still around.
"There was no distance between people," one passenger said.
Another passenger who found themselves stuck in a lengthy line last week having travelled from the UK warned of worse to come over the summer months.
“It's going to be a nightmare this summer at the airport if it's going to be like this," he said.
The queues are being blamed on understaffing at the airport.
Airport workers say there is a shortage of security officers because the contracts they are being offered are unattractive or part-time.
Holidaymakers have taken to the social networks to complain about the queues and the frustration at having to wait so long to get through security.
They are also voicing their fears at being so close together for such a long time.
"Even if you go in plenty of time to the airport, you can find hundreds of people waiting without being able to advance," another passenger said.
The issues have been exasperated by a number of airport buses and holiday coaches arriving at the same time, flooding the queues with weary travellers.
Javier Gandara, president of the Association of Airlines, has called for reinforcements at passport control to ease the problem going into the summer months.
A large part of this traffic is made up of Brits who fly out to join cruise liners at Palma.
“The tourism sector is key to the Spanish economy and for recovery after pandemic, so we see the situation of congestion in airport passport controls unsustainable," said Mr Gandara.
"This problem directly affects passengers but also implies an added difficulty to the already complex operation of airlines and negatively impacts the international image of Spain.
"In fact, this problem of congestion in passport controls has transcended in international media, which could discourage international travellers to come to our holiday country. We cannot afford it."
The airport has been contacted for comment.
