Affiliate disclosure
Buy through a link here and the vendor pays this site a commission. Your price stays the same. The commission comes out of the vendor's margin.
That's the business model.
What the commission doesn't touch
The calculator sorts by the total for your trip, and a commission can't change that sum. It doesn't move a product up a list, change its badge or soften its catch. Carrier roaming passes are listed for comparison whether or not they pay anything.
What you should assume
Not every vendor runs a program like this, so not every link pays. Treat any vendor link as one that might. Prices here carry a check date, and the vendor's checkout wins if the two disagree.
