- Fares
- Half of the 7,070 tickets in the US DOT fare survey for Q2 2025 sold between $125 and $275 one way, median $175. The survey runs a couple of quarters behind, so read it as the shape of the route's pricing rather than today's quote.
- Jul to Sep (Q3 2024): median $175 one way, middle half $100 to $275, 7,672 tickets
- Oct to Dec (Q4 2024): median $175 one way, middle half $125 to $275, 8,037 tickets
