I am based in NA, and flew into London for a meeting.

Afterwards, I had set up a mileage ticket to go to Russia.

However, on the outbound (SAS) it turned out that SAS was on strike (at least on 5/28).

I had zero notice - I did not find out until I'd come into the airport.

Fortunately SAS bought me a seat on BA and all was well - adding on 2 hours of delay.

However, I am now concerned about my return where I'm going LED-MUC-LHR, then LHR-LAX-SFO on my original paid ticket.

If LH is on strike, I'll miss my return paid ticket and really not be happy.

On the other hand, if I know I can possibly make other arrangements.
