I've had a double change to flight times by QR on 30 May:

Departure from BKK to DOH shifted right from 2040 to 2115;
Departure from DOH to ARN has come left from 0130 to 0100.

Net effect is that my comfortable 2 Hr connection has been squeezed to 35 mins. (Outbound leg from ARN-DOH-BKK has also been squeezed from 3h 5m to 1h 5m)

QR are asking me to accept the schedule changes online. Should I do this?. If I do, are QR still responsible for the consequences, or am I partly responsible for my own destiny as I accepted the schedule change knowing that my connection time was reduced to 35 mins (which is 10 mins less that QR's own website says is the minimum)?

looking at alternatives, I could leave BKK 12 hours earlier, but that just gives me 12 hrs in DOH which isn't particularly convenient. I'm flying J and will have checked baggage.
