One route, followed properly: Milan (MXP) to Varadero (VRA), return. What follows is the lowest fare our radar has picked up on it and the precise dates behind that number, rather than a headline price with the conditions left out.
We do not post a price and leave it to age. Each fare is re-checked against Skyscanner on a schedule and carries the time it was last confirmed. Not flying from Milan? We track 1 other departure city for Varadero, listed at the foot of this page.
Cheap fares do not hang around. If this one has already gone, nudge the dates either way by a day or two; Milan to Varadero is usually still decent value around the same window.
