I'm trying to book a one-way economy saver award from SFO-BOS (12,500 miles) and there's no availability direct from SFO, but there is availability from SFO-IAH for the day I want to travel and from IAH-BOS the following day. I thought if you overnighted less than 24h on an award ticket at a hub city it wasn't considered a stopover and the journey would be priced based on a one-way (I've done this on an international one-way award ticket before) but .bomb is pricing this out at 25,000 miles when I search this as a multi-city journey. Is that <24h stopover "rule" only valid on international itineraries or did something change recently?
