I guess it would depend on what your concern is. If you are worried about flying on a Max 8, that would be understandable. However, (and this is just my opinion), given the publicity and scrutiny the Max 8 has been under, I am convinced that it will not be put back into service until it is proven to be totally safe to fly. Given that premise, I personally would not be concerned about flying on the Max 8 once it has been proven safe. If on the other hand you are concerned about the flight being cancelled at the last minute due to the Max 8 still being out of service, I don't think you need to worry. That 12:10 flight out of Miami is a staple of AA's itinerary to SXM and they would just change the equipment used for that flight. Just my thoughts.
