Not that it really matters, but to set the record straight:
On the Paris-Miami flight the crews do run pretty senior. I flew it for 9 years straight as a speaker and it was the second most senior route in Miami-I after Madrid. The crew in question that had Richard Reid on board is a great group of people. Christina, who had her hand bitten, is about a year senior to me so she has about 18 years seniority at AA ( I hope she doesn't read the post that guesses her seniority to be 30 years; she'd seek revenge!). Letty, the lady with long brown hair who was blocking access to the cockpit (as she stated in the interviews) had about 33 years seniority and she subsequently retired (our loss). Carol, the purser, has about 36 years, I believe. Again, not that this matters but the thread began about very senior people and their ability to "hang in there" with this job. Miami does not have the quantity of mega-senior people like Chicago-I or LAX-I have (we have a few very, very senior people but they are the exception), so it is difficult for me to add anything to this subject. I have not flown with anyone with 40 years or more since I was based in Chicago-I a long time ago. However, I would agree that if one's physical shape limits his/her ability to perform the required task, it is time to move on. There is the element of safety and the need to be quick on one's toes if any emergency arises. Having said this, I do not mean to take away from the wealth of experience and knowledge that senior people contribute to this job. The Reid flight is a beautiful example of how many cumulative years on the job allowed this crew to remain cool and to think out of the box and do things that are not "by the book" in order the ensure the safety of the passengers on board. They were simply brilliant. Also, I must say the senior crews have given me the biggest laughs over the years. They can be very crusty yet hysterical at the same time. They have been there and done that and they say it like it is.
