Fares
Half of the 650 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 $250, 648 tickets
  • Oct to Dec (Q4 2024): median $175 one way, middle half $125 to $275, 666 tickets

  • Apr to Jun (Q2 2025): median $175 one way, middle half $125 to $275, 650 tickets
Fares held steady through the year: a median of $175 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.
