Lots of disconnected info in this thread. Here is the facts:
- *IF* Qatar has sold you SIN-DOH-CH-VNO as one ticket, and you have a ticket showing just that then connecting in CPH is no issue.
- In CPH the morning arrival from DOH comes in so early there is barely any people for the immigration, thats done in a few minutes.
- QR/SK partner on tickets if sold together, SK wil honor your ticket if there is a misconnect. As long as it is sold as a single ticket then it doesn't matter who's in which alliance or parter with whom.
- Vilnius is likely leaving from the A gates, so you will get your morning run done.
I do QR/SK connections on a single ticket all the time and there is no problem doing this in 40 mins in CPH in the morning. With the winds being what they are this time of year the DOH-CPH somewhat consistently comes in 10-20 minutes before scheule most mornings, this gives you a few minutes extra.
