Valizim
Valizim takes the guesswork out of packing for flights. Users can input their luggage dimensions or use the camera to quickly measure their bag, then instantly check compatibility with 50+ airlines' carry-on and checked baggage policies. The app shows weight limits, size restrictions, and extra baggage fees for each airline, helping travelers avoid surprise charges at the gate.
