Definition
The TSA (Transportation Security Administration) 100 ml liquid limit for airline carry-on, introduced in 2006, created a strong market incentive for sub-100 ml travel formats. This regulation, combined with the growth of niche travel retail, accelerated the adoption of travel spray formats across the industry.
Refillable travel atomizers (Travalo, Chanel's "Les Miniatures" format) allow collectors to carry multiple fragrances in compact form, creating a secondary market for accessories within the fragrance community.
Formats and uses
Travel formats come in three main types: travel spray (a standalone small bottle with its own spray mechanism), refillable travel atomizer (a reusable spray case filled from a full-size bottle), and discovery set miniatures (5 to 10 ml vials sold as samplers). The 10 ml TSA-compliant format has become industry standard for travel-specific products (Fragrantica, accessed 2026-05-27).
For niche houses, travel formats serve a dual commercial function: they reduce the entry price point (a 10 ml travel spray is accessible to buyers reluctant to commit to a 50+ ml bottle at 150-300 euros) and serve as discovery vehicles. Houses such as Maison Francis Kurkdjian, Diptpyque, and Le Labo have built significant commercial volume from their travel format programs (Basenotes wiki, Now Smell This, accessed 2026-05-27).
