Flight
Merida is a city of over 1 million people, and its airport services over 2 million people annually. Its busiest US-Mexico routes are to/from Houston and Miami. It's about a 15 min taxi ride to the centro, but residents also use Uber to move around the city.
Flight
Flights to Cancun can sometimes be much cheaper than flying into Merida directly. Many expats often fly into Cancun for the cost savings, and then take an ADO charter bus to Merida or catch another flight on a Mexican airline to Merida. Roundtrip bus tickets (depending on when you purchase) can cost anywhere between $30 - $60. The ride is about 3-4 hours, and they run about 4 routes daily from the Cancun airport.
Travel Note
AirBnB is very active in Mexico. Many expats have renovated old colonial homes and they choose AirBnB as their rental platform. You can get whole houses with beautiful pools for cooling off for roughly $50 per person, per night.
