The success of the 737 has been immense but at the time of its development it had a mountain to climb. It would be United Airlines, more than any other, that Boeing has to thank for getting the type past its rough early years to where it is today and the ‘Fat Little Ugly Fella’ i.e. FLUF certainly put in the hard yards over the years for United.
At the end of the 60s the age of the widebody was fast approaching and all the major US airlines were on a new equipment binge. The 747 was the first new widebody and everyone felt they had to have some or suffer the consequences of being left behind. In fact all the trunk airlines operated Jumbos (except for Northeast and Western) although, considering only Pan Am, Northwest and TWA had international routes, they mostly lacked sensible ways to utilise them. Eastern, unusually, went down a more considered path than everyone else but still ended up with 747s for a time.
