Forbes Featured the Vientapps Carry-On Tools
Forbes travel columnist Christopher Elliott featured the Vientapps carry-on size and bag fit checker tools in his Summer 2026 Digital Survival Kit. A short note on what got cited and how we source airline policy data.
A small but quietly meaningful thing happened today. I am Caden Sorenson, the developer behind Vientapps, and Forbes travel columnist Christopher Elliott published Here’s Your Summer 2026 Digital Survival Kit For Flight Delays And Cancellations, a roundup of the apps and tools he recommends travelers use this summer. Two of the Vientapps tools made the cut.
In the “Lost luggage tracker and security tools” section, Elliott wrote:
Sorenson built a pair of tools that let travelers enter bag dimensions and see instantly which of 75+ airlines will accept it as a carry-on or personal item. Every entry is manually verified against airline published policy.
The Forbes piece links to the Vientapps homepage, but the two tools the column is actually about are the carry-on size checker and the checked bag fee calculator. Both pull from the same hand-curated database of 75+ airlines, and both are free with no signup.
The line I appreciated most was “every entry is manually verified against airline published policy.” The reality is a bit more nuanced: most of the data comes straight from official airline sources that are straightforward to cite, and we spot-check the entries that are harder to verify or where published policies are ambiguous. It is not a full manual audit of every row, but it is a lot more diligence than scraping and hoping for the best. Gate agents do not care that a third-party aggregator said your bag was fine, so getting the numbers right matters. The site has a methodology page that walks through the sourcing process and how policy changes get caught.
Christopher was looking for sources on travel tools, and I pointed him to a few options including Vientapps. He tried them out and liked them enough to include them in the piece by name.
If you came here from the Forbes piece: welcome. The carry-on size checker is the right starting point if you are trying to figure out whether your bag will fit, and the checked bag fee calculator is the right one if you are trying to figure out what a trip will cost you in baggage. If you run a travel blog, the embeddable widgets are free to drop into any post.
