Best time to visit Mexico City from Ireland
Mexico City is a popular destination for Irish holidaymakers. Dublin Airport has regular direct or connecting flights year-round. The best time to visit depends on your preferences for weather, crowds, and value.
Airport and Transit Connectivity
Mexico City International Airport (MEX), also called Benito Juarez Airport, is about 5 kilometers from the Historic centre. The airport has 4G throughout its two terminals. The Mexico City metro Line 5 (yellow) connects the airport to the metro network.
Uber operates from the airport but requires booking from the official Uber zone in the terminals. Taxis from authorized airport stands have fixed rates to different zones. The Felipe Angeles International Airport (NLU) north of the city connects via the Tren Suburbano and shuttle buses.
Uber, DiDi, and Cabify all operate in Mexico City and need live data. The CDMX Mi Movilidad transit app for real-time metro and bus info needs a data connection. Irish travellers should activate their eSIM before boarding so navigation apps work as soon as they land.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
