And of course we had to get clear from the A concourse to the C concourse , but the Minneapolis airport has those moving sidewalk things - but I was still huffing and puffing by the time we got to our gate , and the plane took off maybe 15 minutes later . The flight from St. Louis to Minneapolis was CRAMPED . The plane held maybe 50 people , two per side , and it was pretty uncomfortable . We were supposed to be on a Boeing 747 for the flight to Anchorage , but it was a 757 instead .

Answer the following question: Why was the plane ride so uncomfortable ?
There were too many people sitting on the plane .
