A reasonably comfortable flight in cattle class - 747s definitely have more legroom than 777s.

Very young cabin crew. A bit of a lack of leadership

Flight was about two hours late departing, but that worked out great for me, because my thomas cook originating flight was 4 hours late in total.

First time traveling with Alaska Airlines but was pleasantly surprised with their professionalism, courteous and 'can-do' attitude. Will fly with them again, may even become a shareholder!

Main meal was missing starter, butter and cup. In-air service wasn’t as good a Virgin Atlantic.
