March through May is the sweet spot for Mexico City. You get clear skies and warm days, which are perfect for walking through Roma or exploring the markets in Coyoacán. The jacaranda trees are in full bloom, turning the streets purple and making the city feel like a massive garden.
For a trip costing around $380, you can manage the expense by using the Citi Simplicity® Credit Card. It offers 0% for 18 months on purchases and balance transfers from date of account opening. This lets you spread the cost of your flights and stay over a longer window without paying interest.
Remember that the 18-month window is a deadline, not a gift. If you still have a balance once those 18 months are up, the card will start charging interest on whatever remains, which can get expensive fast.
