Aer Lingus is currently offering low fares from Brussels to Cancún, Mexico, starting at €422 round-trip. Even better, you can drop the fare significantly by booking an open-jaw itinerary: flying out of Brussels and returning to Germany from just €372. Remarkably, these open-jaw fares book into a fare family that already includes a 23 kg checked bag (which normally costs €100+ extra).
Availability is solid from November 2026 through March 2027 (blacked out over Christmas and New Year)—making this a great option for escaping the European winter.
Here are several sample open-jaw routings (prices include a 23 kg checked bag):
- Brussels → Cancún → Berlin for €372
- Brussels → Cancún → Munich for €389
- Brussels → Cancún → Düsseldorf for €392
- Brussels → Cancún → Zurich for €443
These discounted open-jaw fares appear to be bookable primarily through online travel agencies. You can use our calendar tool below to explore dates from Brussels and book via Trip.com or Aer Lingus.
