Hi,I think you should be fine sending them through MSP. Any type of routing usually works. I would say that they would rather go on the direct flight, though. why don't you leave things as they are for now, and then, a day before they come home, check the loads, and relist them accordingly. I've done that many times and there is usually no change in fare, and no trouble. At the airport, they can also change to other flights. For example, if the jfk-sea flight were full, I suspect they would just relist them on the next flight (or comibnation of flights) to sea. Let's see if anyone else has any further input on this.
