You aren’t frugal. Do what you want.
OP here, no, I said we generally travel on a moderate budget, but my spouse is naturally frugal. We have a family trip coming up to nyc for a few days and he wants to drive, stay in jersey at a motel to save a few hundred dollars. I'd much rather fly, maximize my time and stay close to where we want to do things. so he would never, ever imagine paying for business class....
anyway, I think we will fly economy, but I am looking into whether we could do a longer layover on the way there in Istanbul on Turkish air. take 1,5-2 days (I've always wanted to go back having gone once many years ago), and then keep going. The way back will be a slog, but it always is. Might be other stopover possibilities as well.
