About CarryOnSize Checker

Our Mission
To empower travelers worldwide with accurate, up-to-date airline baggage information, helping them avoid unexpected fees and travel complications through our comprehensive carry-on size comparison tool.
The Problem We Solve
Confusing airline policies: Each airline has different carry-on size limits, weight restrictions, and enforcement policies.
Expensive surprises: Travelers often discover their luggage doesn't meet requirements only at the airport, leading to unexpected fees or forced check-ins.
Time-consuming research: Comparing baggage policies across multiple airlines is tedious and information is often scattered across different websites.
Outdated information: Many websites provide outdated or incorrect baggage information, leading to traveler confusion.

Our Story
CarryOnSize Checker was born from frustration. Like many travelers, our founders experienced the stress of arriving at the airport only to discover their carefully packed carry-on bag didn't meet the airline's requirements.
After paying unexpected fees and watching other passengers face similar problems, we realized there had to be a better way. We spent months researching airline policies, building relationships with industry sources, and developing the technology to make baggage comparison simple and reliable.
Launched in 2025, CarryOnSize Checker helps travelers avoid baggage surprises and travel with confidence. We're proud to be the go-to resource for accurate airline baggage information.
