Underseater Luggage & Suitcases

Underseater bags are built for the space beneath the seat in front - the personal item allowance that most airlines offer in addition to a cabin bag. Getting both right means travelling with maximum luggage without paying for hold. This collection features compact, structured bags and small suitcases from Tumi, Samsonite, and Bric's that fit within the typical 40 x 30 x 15 cm underseat dimensions. Use one as a standalone day bag, or pair with a full carry-on from our cabin luggage collection. Combining an underseater with a 55 x 40 x 20 cm cabin case is the definitive hand-luggage-only packing strategy.

Case Luggage is a specialist in premium underseater luggage and an official stockist for every piece we sell. We work directly with established travel goods brands and focus on collections designed to meet strict airline personal item requirements while maintaining structural durability in compact formats.

Underseater luggage may be the dark horse of the luggage family, but it demands disciplined engineering and rigorous product selection. Construction integrity is non-negotiable in this category. Our underseater collection is vetted for structural stability, ensuring performance when space is limited and pressure is applied.

Our evaluation prioritises long-term durability, proven brand heritage, and dependable aftercare support, recognising that compact formats often work harder than larger cases. A well-engineered underseater retains its form under load, maintaining airline compatibility and delivering consistent performance across repeated journeys. That is the standard we set for every piece within this collection.

For over a century, Case Luggage has worked with leading international luggage brands, building long-standing relationships based on quality and trust.

This guarantees:

  • Authentic underseater products supplied through authorised channels
  • Full manufacturer warranties
  • Recognised aftercare support
  • Verified customer trust

Our expert team is available to help you with your journey to buying your next underseater, and our information hub is also available to dive deep into everything luggage.
