I did the commute back in 98-01 was not bad ORD based living in Orlando but at the time we were running 10 flights a day all mainline majority were 757's we had the noon ORD DC-10 flight that switched over to the 763, a few 727 and 733 flights. I could easily get to ORD on the 6am flight it was normally half full on a 752. if I waited for the 7am it was normally pretty full. These days I would never want to commute seeing how everything out of MCO is normally full on the 739, even the 753 that left 45 minutes later.
