Ever splurged on a window seat for your flight, only to find yourself staring at a blank wall? Some United and Delta passengers are suing after paying up to $169 extra for 'window' seats with no actual window. The airlines say 'window seat' just means 'next to the wall,' not a guaranteed view. Pro tip: Check seat maps or book with airlines that show if your window seat actually has a window! #Business #travelhacks #airlinetips
