Hello all, I'd like to book a flight from JFK to GUM with a week layover at NRT. Booking the flight through Delta I was able to find a business class seats for around $3,500 but it is with an hour layover at NRT. When trying to schedule it as a multi-segment trip the price jumps up to about $6k per ticket. I've seen a lot of talk about scheduling layovers to plan your perfect trip... but how do you go about scheduling it? can it be done online or do you have to go through an airline agent? Thanks in advance!
