I have a flight GVA-ZRH on LX and then on to HKG with CX, but I can't see to check-in online neither on the CX website nor on the LX website.

Is it because I am traveling to a country outside Schengen? Or do I have to wait 24-hrs before the LX flight?

Could it be a system glitch? I even received an email from LX inviting me to check-in online and even print my luggage tags.
