To take the guesswork out of packing, we’ve created an easy-to-use tool and a full list of cabin bag and under-seat bag allowances across major airlines, including British Airways, easyJet and Ryanair. This includes both size and weight limits so you can quickly check what’s allowed for your ticket type.

Compare luggage sizes, weights, and costs across airlines

Finding the right cabin or hold baggage allowance can be tricky, with each airline setting different size, weight, and price rules. Our luggage comparison tool makes it easy to compare baggage policies across multiple airlines at a glance.

We’ve gathered data from official sources to ensure accuracy. For clear visual comparisons, we've standardised luggage dimensions where airlines use total measurements (height + width + depth). Costs are converted to GBP for consistency, giving you a hassle-free way to check extra baggage fees before you book.

Use the tool to find the best luggage options for your trip—without any surprises at the airport!

Disclaimer: The baggage allowances shown in this tool are based on Economy class fares. Allowances may vary depending on airline, route, travel class, and fare type. All dimensions provided include handles and wheels.

Conversions are accurate as of March 2025. All sources and links to official airline pages can be found directly within the planner or the table below.
