How do you know your flight was cancelled if you have not been notified by the airline?

If it was, just call and tell them you want to make sure you get to your final destination on time (because of an essential business meeting etc.) and would prefer a longer layover.

Source the alternative that suits you & then talk to AV it is their ticket.

I just found out by chance as I looked up my booking on the app. It's never a good feeling when you are not notified of a change that could throw your plans up in the air...

yes, I was wondering how this would work. To clarify it is an LH flight SFO-MUC in O class and MUC-GVA in I class booked with AV Lifemiles. Since it is LH who cancelled the flight shouldn't it be LH who rebooks me and handle this with AV internally in terms of ticketing? Technically, I shouldn't have to do anything to rectify this issue (except in this case I would like to get a preferred outcome)
if i call AV to rebook, if there is space, they would just charge me the $200 change fee no? And they certainly wouldn't accommodate any request to prolong lounge enjoyment time...! I think the onus is on LH in this case as it is their schedule change.

i had an identical situation with a BA award booked through AA. Again, no notification, just found out by chance when I tried to add the booking to my BA app. Called BA, they rebooked me (even opened up revenue inventory) to accommodate me, reissued the ticket on BA stock. Funny thing, a month later I got an email from AA with the new flights but with AA ticket number. So I guess there was some internal process where AA took the new flights and reissued the ticket (again) on their stock...?

Many thanks to everyone who replied and offered their thoughts...
i see that LH has a First Class hotline, does anyone have experience with the service and what are the general thoughts on this?

Wait times are usually shorter and service is better on the F line, so just check it out.

I would be very open with them and say that I am worried about the short connection as reaching my final destination on time is essential.

So, for those curious how this was resolved:
i called the LH First hotline, (very long wait times!) and they somehow had trouble confirming me for the flight with only 40 mins connection, which suited me perfectly. The system wouldn't confirm although it's a legal connection. Anyway, the agent offered the following alternative: LX F via ZRH! That's like striking the jackpot as far as I'm concerned as LX F is off limits (I'm not a member of Miles & More)
next question is the lounge access in ZRH as I've read many reports of LX denying F pax on their flights lounge access if booked on codeshare. (I know I'm not codeshare but just wanted to check to avoid bad surprises) Since I'm at ZRH right now waiting for another flight, I walked from the SEN lounge to the F lounge to ask personally if my situation would allow access. (LX flight number, F cabin, award on partner ticket stock) it took 3 lounge employees (including a supervisor) to confirm that as long as I had a boarding pass in LX F, I would be granted access. It seems that since a few months, they have abolished their very 'bünzli' rule of denying pax on LX F metal access just because they booked on a codeshare.
So all in all I think a very good resolution.
Thank you to all who participated in this discussion.

Good result 👍

So who reissued your ticket ?

I think it's LH/LX because it's 220 now...or maybe they'll coordinate with AV later and reissue again as 202...let's see!

Sounds like you got all you could ask for. Excellent!

220.... that’s LH I doubt LH will talk with AV
