9/11 Misses

The two most famous cases of "celebrity who was supposed to be on one of the 9/11 planes" are Seth MacFarlane:

On the morning of September 11, 2001, MacFarlane was scheduled to return to Los Angeles on American Airlines Flight 11 from Boston. Suffering from a hangover after the previous night's celebrations that followed his speech at his alma mater, the Rhode Island School of Design, and with an incorrect departure time (8:15 a.m. instead of 7:45 a.m.) from his travel agent, he arrived at Logan International Airport about ten minutes too late to board the flight.

"The only reason it hasn't really affected me as it maybe could have is I didn't really know that I was in any danger until after it was over, so I never had that panic moment. After the fact, it was sobering, but people have a lot of close calls; you're crossing the street and you almost get hit by a car... this one just happened to be related to something massive.

and Mark Wahlberg:

Wahlberg was booked to fly on American Airlines Flight 11 on September 11, 2001, but his plans changed the day before and he canceled his reservation. He received backlash for stating in a 2012 interview, "If I was on that plane with my kids, it wouldn't have went down like it did". He added that "there would have been a lot of blood in that first-class cabin and then me saying, 'OK, we're going to land somewhere safely, don't worry.'" He issued an apology after family members of those killed on the flight expressed outrage^.

Typical Markie Mark dumb bluster. Meanwhile, MacFarlane's turn later on was also typical of himself: he wrote the incident into a Family Guy episode.

Is this what brought them together for Ted? Did this come up while they were shooting? HOW COULD IT NOT?!!?!?!?!
