Bag fees on this route

What the airlines flying Houston to Denver usually charge for one bag each way. Budget airlines often sell the cheapest fares and charge the most for bags, so compare the total, not the fare.

Our estimates: fees depend on the fare type and when you pay. Check the airline's own price when you book.

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).
