There are two main types of small luggage commonly used for air travel: underseat and overhead luggage.
Underseat luggage, typically around 45 cm x 35 cm x 20 cm, is designed to fit under the seat in front of you. This compact size is ideal for personal items and essentials you want to keep close during the flight.
Overhead luggage, usually around 56 cm x 35 cm x 23 cm, is larger and meant to be stowed in the overhead compartment. It's perfect for short to medium-length trips, allowing you to carry more without the need for checked baggage. Both types are designed to comply with most airlines' in-cabin restrictions. Db offers a variety of small overhead luggage above and smaller backpacks and totes to be used as under seat bags.
