Best time of day to fly it
Delays cascade through each aircraft's day — morning departures have been this route's safest window (29% on-time). For a client with a connection, book early.
Whose fault are the delays — airline or weather?
Every one of the window's 86 operations flew in clear conditions at LHR — and the route still averaged 37 minutes of departure delay. That matters legally: clear-day delays are the airline's responsibility, with no "extraordinary circumstances" defence — exactly the delays where EC261/UK261 compensation (€250 / £220 per passenger on this route) applies.

Qualifying events: 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 LHR (tight turnarounds are how one late arrival cascades all day).
Agents ask
Which London to Paris flight is the most reliable right now?
Air France AF1381 (the 06:15 departure) has run the cleanest — median 12 minutes of departure delay and 71% on-time across its last 7 operations, with no cancellations.
Which flight from LHR to CDG is delayed most often?
British BA306 (12:50) has been the route's weakest recent performer, running a median 81 minutes behind schedule.
What is the best time of day to fly London to Paris?
Morning departures have performed best recently — a median 24 minutes of delay and 29% on-time across 38 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 LHR–CDG flight?
The LHR–CDG corridor is about 347 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: Air France or British?
On recent form, Air France leads: median 24 min delay and 33% on-time across 42 operations, vs British at median 40 min and 10% on-time.
Can my client claim for a past LHR–CDG disruption?
Often yes — limitation periods reach back years (up to six in England & Wales, five in France, three in Germany). If a client's LHR–CDG 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.
