Will my white label portal work properly on mobile phones, since most of my customers search on their phones?

Yes, your white label portal is built to work on a mobile phone as well as on a desktop computer. It is the same website, and it rearranges itself to fit the size of the screen it is opened on, so someone on a phone gets a search form, a result list and a booking page that fit the screen and can be tapped with a thumb. You do not have to build or pay for a separate mobile version of your site.

A few things do behave differently on a small screen, and it is fair to know that up front. Long hotel result lists and detailed fare breakdowns show less at a glance, so your customer may need to tap into a result to see everything you would see side by side on a laptop. Pages that come from outside the portal, such as a payment page from a bank or a supplier page a customer is sent to in certain booking flows, are controlled by that company rather than by us, so how neatly they behave on a phone depends on them.

Whether you also get a phone app, instead of a mobile friendly website, depends on your plan, so please check before you promise an app to your customers. Anything you add yourself is worth checking too. Your own banners, large images or extra landing pages can slow a page down or push the layout out of shape on a narrow screen, even when the rest of the portal is fine.

The simplest next step is to open your own portal on your own phone and run one real search and one test booking all the way through, on both a flight and a hotel. If a page looks wrong or a button is hard to tap, note which page it was and which phone and browser you used, and raise it so it can be checked properly.
