If it were on a plane I would be just a tad concerned
All airports have multifaith prayer rooms so not sue why anyone would want to pray in the middle of a busy airport and not avail themselves of a bit of peace and quiet but if thats what they want to so, no issues, as long as praying in public is tolerated for all faiths of course...
