Just booked a friend on her no status account MCO-SLC-SEA for 11K of her 11767 miles in Basic Economy (she won't be checking luggage). OTOH, she has a 34 minute connection to the last flight of the day SLC-SEA.
This will be on time I will be advising her to try to get a seat further forward in the MCO-SLC plane on check-in even if it is a middle seat. This flight isn't until July 2020, so I suspect schedule changes may result in getting an improved connection times or a better routing.
