183 Mexicans are stranded at Madrid-Barajas airport, some for up to two weeks. They are sleeping on the floor and are running out of money to buy food.
They are grounded because the kind of tickets they are holding are honored only on non-full Aeromexico flights, and since it is tourist season, all the flights have been full.
A Facebook group called Mexicanas en Madrid issued a public appeal for help.
"It would be good to supply them with food, drinks, damp towels, spare bottles for water, fruit," their post said, adding that offers of temporary accommodation would be welcome too.
El Pais newspaper said some Madrid residents had offered to put Mexicans up for a few nights.
