Irish people travelling to six Spanish airports this summer have been warned to brace themselves for chaos.
The tourism alliance, Exceltur, pointed to the airports of south and north Tenerife, Gran Canaria, Malaga and Mallorca for special warnings.
The organisation says there will be 'significant and major chaos' at these airports.
And Exceltur says 'urgent' action needs to be taken at border controls to try and improve the situation.
Vice president of Exceltur, José Luis Zoreda, puts the chaos down to high levels of tourists arriving, particularly British tourists.
Mr Zoreda said lack of personnel was to blame and also pointed to the impact of the Ryanair, easyJet strikes and multiple flight cancellations.
He has urged the Ministry of the Interior to make sure there are all the necessary police resources at the main tourist airports and in Madrid-Barajas to facilitate passport control to alleviate the issue.
"These are causing remarkable dissuasive problems and inconvenience to tourists who want to fly to Spain," he said.
Exceltur did not place the blame on Spain's airport authority, AENA, instead saying they have shown "great professionalism."
"The Ministry of Interior must provide the necessary means so that Spanish airports continue to stand out as the best gateway for tourists to enter and exit our country."
People have been warned to expect further delays and airport congestion as Ryanair walkouts have been proposed from July 12 to 15, July 18 to 21 and July 25 to 28, affecting ten bases - Madrid, Malaga, Barcelona, Alicante, Sevilla, Palma, Valencia, Girona, Santiago de Compostela and Ibiza.
Further easyJet strikes will then take place between July 15 and 17 and July 29 and 31.
