Translation of lamprey in Spanish

At noon we drove back to the tiny airport near the city and a few moments later we were already in the skies. The flight to Saigon, today's name Ho Chi Minh city, lasted more or less one hour.
The city seemed to be small but busy and many building were new. It looked like a third world country village with four and five star hotels. The infrastructure was still bad, but one could see development.
The next day we had to take the bus in order to get back to the airport in Calama. When we arrived at the airport was empty and no counter was open yet. We had to wait for 4 hours.
