Not sure what the $29 is for "AA door to door" but in the end, that is probably not going to change anything with flight arrival and departure times.

I did some quick research for the "door to door" service and it appears it is an independent contractor to handle your baggage? Not trying to question what you have chosen but as I earlier stated, this will not impact flight schedules at all.

"Door-to-door baggage service
Do you prefer to 'travel light' and avoid the need for queuing up at the check-in or Bag Drop desks at the airport?
We provide a service, in conjunction with our partner First Luggage, where your luggage can be collected from your home or office prior to your departure and then delivered to your destination, irrespective of your class of travel."

Good luck.
