Is there a dress code in business class?

In upscale hotels, the dress code is clear: guests wear long trousers to dinner, and open shoes are not permitted. For gala dinners, a jacket and tie are usually required for men, and elegant evening gowns for women. Dress codes are also still considered good form on cruise ships, especially for dinners in stylish settings.

Dress codes have long been ingrained in travel culture — symbols of style, respect, and a sense of belonging. But what about above the clouds? While luxury hotels and elegant cruise ships have clear standards, air travel seems to allow for a touch more informality. Or is that just an illusion?

Business class travelers, after all, enter the premium realm of flying — complete with champagne flutes and lie-flat seats. So, does this rarefied space come with its own dress code? And if so, what should one wear — and what’s best avoided?

How relaxed can it be?

Swiss takes a relaxed approach to the dress code. «We don't have an official dress code for passengers – not even in Business Class,» Swiss media chief Michael Weinmann told Travelnews.

The well-being of the guests is paramount, regardless of whether they are traveling in business attire or casual wear. «The only crucial factor is that the clothing is respectful and appropriate for the setting,» Weinmann continued.

The cabin crew has no specific guidelines regarding passenger attire. Intervention would only occur in very rare exceptional cases – such as offensive or unhygienic clothing – to ensure the comfort and well-being of everyone on board, explains the Swiss media spokesperson.

Weinmann generally recommends comfortable clothing, especially on longer flights. In recent years, the dress code of many business class travelers has become significantly more relaxed. The trend – as in many other areas of life – is moving towards «business casual,» where the focus is more on comfort than on formal attire.
