History, not a price to book: what the average passenger paid per one-way trip in each quarter (Q2 2025 $238 · Q3 2025 $226 · Q4 2025 $270 · Q1 2026 $302).
Fare outlook, Q1 2027: about $308, likely $267–$352
The average fare paid we expect a year after Q1 2026, the newest DOT quarter. On this route, past forecasts made this way fell inside the range 90% of the time over 21 quarters (median error 7.8%). An estimate from US DOT data: not a price you can book, not a guarantee, not advice on when to buy. How the outlook works
Cheapest quarter on this route: Q3, typically 6% below the year's average (9 years of DOT data, without 2020–21).

Delay compensation (EU261 / UK261)
Measured by great-circle distance: 1,405 km.
Neither EU261 nor UK261 covers this route: it neither starts nor ends in the EU, EEA, Switzerland or the UK. Other countries have their own rules (for example Canada's APPR or Brazil's ANAC rules).
Also owed for a cancellation with less than 14 days' notice or denied boarding. Not owed for extraordinary circumstances. On a connection, the distance to the final destination counts. From 23 October 2027 the EU's Regulation 2026/2202 applies; it keeps these amounts (what changes in 2027). Information, not legal advice.
