The colorful umbrellas that line the San Antonio river walk are similar to the ones lining the beaches of sunny Cancun. In fact, San Antonio has a large Hispanic population, with several aspects of the Mexican culture making up the city’s character. As such, the similarities between the two cultures of San Antonio and Cancun make the Mexican destination appealing for San Antonians. Plus, Cancun is less than three hours away, which is a shorter travel time than several domestic flights. These tips from Hopper can help locals find cheap flights from San Antonio to Cancun, making the trip not only easy, but affordable, too.

1. The cheapest time to book a flight from San Antonio to Cancun is 30 days in advance, saving up to $100

Although Cancun is closer than some domestic destinations, planning your trip well in advance is still important. In fact, you can save up to $100 by booking a flight 30 days in advance. Ticket prices really start to spike within 14 days of your departure date. Planning in advance also allows you to figure out exactly what you want to do on your vacation. Visiting the Mayan ruins, for instance, can take at least half a day, so you may want to try to book a tour well in advance.

2. The cheapest time to fly from San Antonio to Cancun is anytime not in April or May – save up to $20

By not traveling to Cancun in April or May travelers can save you up to $20 and avoid the spring break crowds and high prices, too. Prices the rest of the year are pretty flat, so any other time is a good choice for travelers.

3. The cheapest day to fly from San Antonio to Cancun is on a Tuesday, saving up to $22

Tuesdays tend to be the best days to travel because they’re the least busy, and you can save up to $22 in doing so. While that’s not a huge savings, it can add up for families and there are typically midweek savings to be found at Cancun's beach resorts, too.

4. Save up to $21 by returning on a Tuesday

As such, returning on a Tuesday is equally as convenient and can save travelers up to $21. This is perfect if you are looking to take a week-long vacation. However, if Tuesdays do not work for you, the savings is not extreme. The good news is you can rest assured that booking the San Antonio-to-Cancun route (or vice versa) on any day of the week is not going to be that much more and may be more convenient for your travel schedule.

5. The cheapest day to buy a flight from San Antonio to Cancun is on a Friday, saving up to $32

Yes! Fridays usually indicate the weekend (unless you have a less conventional work schedule). But before you start figuring out which happy hour to check out to celebrate with some end-of-the-week bubbly, book a flight to Cancun. That weekend mindset is perfect for booking a vacation, and it can save you up to $32 just by buying it on the right day of the week.

9. Take a look at Hopper’s Airline Fees Calculator to get the real cost of your ticket
