How Farepop finds cheap flights to Phnom Penh
Compared with the usual price
Every fare is compared with what the same route usually costs for the same trip length and dates. Around busy holidays we use quieter neighbouring months, so a peak price never passes for a saving.
At least 25% below
A deal is at least 25% below the usual price for those dates, and a good fare at least 20%. Full-service airlines selling at budget prices, and travel agents undercutting the airline, are labelled as such.
Checked twice, then again
Fares are checked again on their exact dates before you hear about them, and regularly after. Ones that no longer qualify are withdrawn.
You book direct
Farepop doesn't sell tickets. Tap a deal and book with the airline or travel site; always check the final price, baggage and conditions before you pay.
