Take distance of the downgraded leg over the total distance, multiply that fraction by 75% and the cost of the ticket ex fees and charges that don't vary with travel class (e.g. airport fees etc.) - unless the booking allocated a specific part of the fare component to the leg in question. So not very much

Recent ruling in last few weeks on this at CJEU

You were still leaving more than 1 hour early for your trip in second instance, the amount should be based on trip length I believe, not leg length

We don't know the cause, so it may be your aren't due anything, though the evidence in your particular case looks to be more equipment/crew shortage. The first one is 125€, the second one is open to debate in application (though I think the Regulation plus case law is clear), but 125€, 250€ or 300€ according to total distance on the great circle basis from start point to end point.

Indeed, probably almost nothing. I'll do a full posting of the implications in a few days, but you can no longer read the advice in this thread as correct, since the CJEU has ruled very strongly in the airlines' favour late last week. In the case of CPH - LHR the won't be much to it, since there are no carrier surcharges or APD differences on that route, so taxes stay the same and are excluded from the calculation.

Thanks all.

I will try for compensation outwith eu262 initially then.

Out of interest, what would you deem appropriate for a downgrade CPH-LHR?

I thought I had my head around all this stuff but not sure about this one...
Flight EDI-LCY cancelled and auto rebooked on a LHR flight 6.5 hours later (a Monday morning so nothing else available) not suitable so opted for refund and booked on flymaybe. Refund received.... assuming reason for cancellation not extraordinary...does EU261 comp apply? (I know you can opt not to travel after 5 hour delay and receive refund + comp but not sure about cancellation and rebook being 5+ hours later)

Not read the judgment but did it say anything about carrier surcharges being included in the calculation or not?

If they are excluded I can see some airlines reducing the base fare and just increasing the surcharge (until some one spots it and takes a case to court and wins)

I'll put more on this later. But there are two features here: surcharges sometimes vary between cabins (though not in all cases). That aspect should not be controversial, the passenger should get that delta back if it applies. The other aspect is the wording in this new judgement, which said this (36):

"Those taxes and charges are unavoidable components of the final price to be paid by the passenger in order to avail of the service proposed by the air carrier"

Carrier surcharges are as avoidable the base fare, to my mind, but that may require further legal clarification.

Thank you corporate-wage-slave - it was a simple delay to a transatlantic flight, which led to a missed connection from LHR to the regions (despite running flat out through T5 - I suppose it woke me up!). I was rebooked onto a later connection that day, but that put my final arrival at 4 hours past my scheduled arrival.

I'll dig out the case reference, check the date I submitted, and follow your advice. Thank you!

I'm not sure if this is a valid claim or not, so any thoughts would be appreciated.

Was booked on an overnight JFK-LHR-SVG. JFK-LHR was delayed due to mechanical issues and got in about 45 minutes late, and then we taxied for a while & they deplaned the 747 using buses and my 1:30 scheduled connection was blown due to the late arrival, mixed with the use of buses to deplane, I didn't even get to the FastTrack passport/ticket checking line til 8:10am and I would not have made for my 8:30am departure.

I was scheduled to arrive in SVG at 11:10am, local time and then I had a later flight (separate ticket) to Amsterdam.

The agent that helped me wanted to put me on the later afternoon SVG flight (that would have gotten to SVG around 5:15pm) - had I taken that, I would have missed my flight to AMS and had a forced overnight in SVG (not BA's problem, I know).

I was able to convince the agent to put me on a KLM LHR-AMS flight that left LHR at 12:35pm and got into AMS at 2:55pm. That flight was on time (landed at 2:41pm, at the gate by 2:55pm).

I'm not really sure if a claim exists here.

I'm not sure I'm going to even file a claim, but I'm wondering whether this would qualify.

I was originally supposed to get to the final destination at 11:10am, but arrived at 2:41pm, so 3:31 later - but, they allowed me a free change to my destination (I was flying in paid business class).

Is this a valid claim?

Thanks!

Could you just clarify the quoted paragraph, I can't get it to compute with the rest of your post. But broadly speaking, if you re-engineered (and reticketed) your booking you may be deemed to have reset the clock.

BA just advised over night that they are paying out for my delay on June 24. This was my first EU261 claim and am surprised at how easy it was, and how quick BA settled.

For others who got caught up in the mayhem last Friday and who may have been put off claiming by BA flight crew, ( mine tried to blame weather and ATC from the day before) BA clearly accepting responsibility and part of their reply to me stated
"’ve looked into the details of your complaint, and from what you and other customers have told us, we didn’t keep you as informed as we should have. Our airport managers meet often so they can look at ways we can improve our service."
Thanks to thread the £206 will in some way make up for the delay.

What is the situation for a claim when a flight is classed as delayed for 22hrs due to no aircraft being there?
Not me this time, but asking for a family member who for some reason decided to fly VS yesterday and is not enjoying being in a hotel somewhere in NJ.

In this case it was EWR-LHR (VS2) last nite.
The inbound aircraft (VS1) was almost at EWR then diverted to BOS, and then kept at BOS overnite - I suspect due to crew out of hours after the divert and the original delay in leaving LHR.
Will it be dismissed instantly due to the storms, or is the fact that there was no aircraft actually there for her flight sufficient for a claim?

EWR isn't a base for Virgin so you can't presume it has the ability to find and lay on an extra aircraft. It will depend on the reason for the diversion to BOS, if that was weather related, as you indicated, I don't think this is going to go anywhere. If, on the other hand, it was due to a technical problem at LHR or en route then you may have a case.

Sorry - multiple typo!

Original itin was JFK-LHR-SVG & the agent at LHR put me on LHR-AMS on KLM instead of LHR-SVG later. Also, ex-LHR, not NYC - I'll edit the post!
