Last November a plane was grounded for five days after more than 130 hamsters in the hold managed to escape their cages as maintenance workers tried to round up the power-eating rodents.
Newspaper La Voz de Galicia said some passengers still checked their surroundings for fear other spiders had got onto the plane, even after fumigation.
Baggage handlers found that the hamster cages had been damaged and that more than 100 were roaming around the cargo hold when the Airbus 320 touched down in the Azores archipelago capital Ponta Delgada on Sao Miguel Island.
In happier travel news, train passengers from Surrey to London were excited to see a four-legged friend hitching a ride to the big city.
Maintenance workers had frantically tried to round up the rodents since Tuesday before they chewed through the plane’s wiring.
