I said this on another thread but travel companies will not survive July/August without package holidays/flights happening, and despite what Spanish authorities say many parts of Spain will not survive without British tourism, and by British tourism I don’t mean the muppets that sit around drinking €2 pints all day in Benidorm so parts of Europe and airlines are going to pull up trees to get some kind of tourism up and running.
Everything depends on the next 2/3 weeks imo, if Spain and the rest of Europe continue to see a decline in fatalities and cases then air travel will be likely back on the cards for summer, with precautions, if there is a second wave then absolutely no chance, unless a drug is developed to treat COVID.
Further afield places like Barbados GDP is 45 percent tourism some hotels are allowing check ins already.
