After testing the flight-specific ads with Cathay Pacific and Delta, now all airline advertisers and online travel booking firms, like Kayak and Orbitz, can run Dynamic Ads for Travel for Flights globally across Facebook, Instagram and Facebook’s Audience Network ad network. The ads can be bought through Facebook’s advertising API or its Ads Manager and Power Editor self-serve ad-buying tools. Advertisers can pay based on the number of clicks or impressions their ads receive, with the option of using Facebook’s optimized CPM (oCPM) that charges brands by impressions and tries to aim those impressions at people most likely to click on them, according to an explainer of the new ad format posted on Facebook’s site. Despite the long-winded name, Dynamic Ads for Travel for Flights are pretty simple. Facebook figures out that a person is looking to travel, including an idea of where and when; Facebook shows that person an ad from an airline promoting an available seat to fly to that place around that date. In addition to flight details like dates and airport names and a link to the advertiser’s site or app, the image-only ads can feature a single photo or a carousel of up to 10 photos, and advertisers have the options of including destination-specific photos, as well as the seat’s price. If an advertiser just wants to use a single image for all of its ads regardless of destination, it can, but it has to go through an ad-buying firm that’s in the Facebook Marketing Partners program.
