Managers at Newcastle International Airport are taking advice from the Health Protection Agency ahead of the resumption of flights to Mexico.
Officials are discussing the possible threat posed by the outbreak of swine influenza in Central and North America, with Mexico City thought to be "ground zero."
The move comes as weekly flights to Cancun, Mexico, are scheduled to start operating with Thomson from Monday May 4.
An airport spokesman said: "At present, there are no changes to flights and holidays to the affected regions.
"However passengers with queries or concerns are advised to contact their tour operator for information and advice.
"Newcastle International Airport will continue to work with the HPA and will take immediate action if official travel and health advice changes."
She added: "Passengers returning from a visit to an affected area are advised to monitor their health closely for seven days.
"If during this period they develop a feverish illness accompanied by one or more of a cough, sore throat, headache or muscle aches, they should stay at home and contact their GP by phone or seek advice from NHS Direct (0845 4647)."
