How these prices work
These are real round-trip fares that travelers found on Aviasales recently, not a live search, so they can change or sell out. Dipt adds an estimate of each airline's carry-on fee, so a cheap fare with expensive bags doesn't look cheaper than it is. "Live price" opens Dipt's live flight search for those dates, where you book with the airline or travel site you pick. Dipt may earn a commission when you book, at no extra cost to you (how Dipt makes money).
