- Fares
- Half of the 12,626 tickets in the US DOT fare survey for Q2 2025 sold between $100 and $250 one way, median $150. 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 $150 one way, middle half $100 to $250, 14,079 tickets
- Oct to Dec (Q4 2024): median $150 one way, middle half $100 to $250, 12,365 tickets

- Apr to Jun (Q2 2025): median $150 one way, middle half $100 to $250, 12,626 tickets
Fares held steady through the year: a median of $150 one way in every quarter of the DOT ticket survey (Q3 2024 to Q2 2025). Bars show the middle half of one-way fares; the mark is the median.
