Restaurants and historic places were the two most popular categories that Facebook users "checked-in" on the social network in the summer season of 2016.
Data released by Facebook, also covering sister photo-sharing site Instagram, coincides with a ramping up of efforts to target travel brands with its Dynamic Ads platform - with airlines added last week to the sectors now included in the programme.
The report into activity during the US's warm months last year indicated that 92% of all "summer-related conversations" took place via mobile device.
Following leading check-ins, restaurants and historic places, came bars, parks and recreational activities as the most popular categories.
On both Facebook and Instagram, travel is the fourth most popular topic of conversation.
Travel-related topics experience a "spike" on Saturdays, Facebook says.
