Can my white label travel portal be shown in more than one language for customers in different countries?

Yes, a white label travel portal can be shown in more than one language, and your customers can normally pick the language they want from a menu on the site.

The parts that belong to your portal, such as the search boxes, the buttons, the wording on the booking steps and the confirmation emails, sit as text in your own setup, so they can be prepared in whichever languages you sell in. Once a language has been added, a customer who lands on your site can switch to it and stay in it all the way through to payment.

The part that is harder to promise is the supplier content. Hotel names, room descriptions, fare rules and airline conditions reach your portal from the supplier or the API, and they arrive in whatever languages that supplier chooses to send. Many suppliers send English only, some send a small number of major languages, and the coverage can differ from one hotel chain or airline to the next. Where a translation has not been sent, that text will appear in the language the supplier gave, even though the rest of the page is in the language your customer picked.

It is also worth remembering that adding a language is a commitment as well as a setting, because your terms, your emails and the replies your staff send should all match it. Before you decide, write down the languages your customers actually book in, then ask which of those your suppliers can supply content in, so you know in advance which pages will read fully in that language and which will be a mix.
