For $431, you get the cheapest fare, but the trip takes 27 hours! For $5 more, you cut that to 19 1/2 hours! Splurge and get a ticket for an 18 hour trip, but pay $2165.
If these fares are for basic economy, plan to sit in a middle seat for that lengthy trip. The cheapest airlines listed I have not heard of, but ANA is $498.
Oz, how much room do you have for guests who accept this invitation of yours?
