ICN-NRT-LAX
LAX-JFK-BOS
Then on the return BOS-JFK-NRT-ICN
All for $3k. OMG, I get to fly JL F twiceeeee
The thing is, my return leg is on February while my intended date is in December. Since this book to the highest fare F, I should be able to make free date change after my first flight, right? Do I have to pay any fare difference
Thanks Flyertalk!!^
