Best time of day to fly it
Delays cascade through each aircraft's day — morning departures have been this route's safest window (65% on-time). For a client with a connection, book early.
Whose fault are the delays — airline or weather?
27% of the window's operations flew on disruptive-weather days at BOS (clear days averaged 34 min of delay; weather days 85 min). Weather days hand airlines an extraordinary-circumstances defence — but the clear-day delays are on the airline, and those are the claimable ones (€250 / £220 per passenger on this route).

Qualifying events under EC Regulation 261/2004: arrival delays of 3+ hours, cancellations without proper notice, and denied boarding — when the cause is within the airline's control. Claims reach back years (up to six in England & Wales). Most go unclaimed because nobody is watching. MyAirAdvocate watches every booking a travel agent forwards and prepares the claim automatically — evidence included.
THIS PAGE IS A SNAPSHOT — ROUTE IQ IS LIVE
Inside the portal, agents run this analysis on any route, on demand — with each flight's day-by-day pattern, per-day weather attribution, and every airline's turnaround discipline at BOS (tight turnarounds are how one late arrival cascades all day).
Agents ask
Which Boston to New York flight is the most reliable right now?
VJA VJA343 (the 13:45 departure) has run the cleanest — median 0 minutes of departure delay and 100% on-time across its last 2 operations, with no cancellations.
Which flight from BOS to JFK is delayed most often?
JetBlue B61117 (20:08) has been the route's weakest recent performer, running a median 118 minutes behind schedule and cancelling 2 of its recent operations.
What is the best time of day to fly Boston to New York?
Morning departures have performed best recently — a median 12 minutes of delay and 65% on-time across 43 operations. Delays compound through the day as late aircraft cascade, so earlier is usually safer for connections.
How much compensation for a delayed or cancelled BOS–JFK flight?
The BOS–JFK corridor is about 300 km (under 1,500 km), so qualifying disruptions pay €250 per passenger under EC261 or £220 under UK261 — per passenger, so a family of four is owed four times that. Delays must reach 3+ hours at arrival; cancellations and denied boarding have their own rules; airline-controlled causes only.
Who is more reliable on this route?
On recent form, VJA leads: median 0 min delay and 100% on-time across 2 operations, vs JetBlue at median 42 min and 35% on-time.
Can my client claim for a past BOS–JFK disruption?
Often yes — limitation periods reach back years (up to six in England & Wales, five in France, three in Germany). If a client's BOS–JFK flight was delayed 3+ hours or cancelled in recent years, the claim may still be live. MyAirAdvocate checks past bookings automatically when agents forward old confirmations.
Methodology: grades weigh on-time percentage (55%) and median departure delay (45%) across all tracked flights, ops-weighted; cancellations are heavily penalized. Source: departure-board telemetry — the same evidence MyAirAdvocate cites in EC261/UK261 claim letters. Short windows are honest but noisy; grades update as new operations land.
