I’ve been flying for a very long time. Not as long as some folks but I was a frequently flyer back when they still let people smoke cigarettes on the plane. Back in those days, the airports did not offer many amenities. In many airports there was only one dining opportunity. Today, the airports have all of the major fast food chains and even some upscale restaurants. Not to mention all of the retail outlets. There is a Brooks Brothers in Terminal D at the Dallas Fort Worth Airport.
