Just an update...LX is still not showing online, and first level phone agents are not able to book either. However, when I escalated to a supervisor, she went through what she called a "backup system" and was able to confirm three business class seats that were showing on United, ANA and ExpertFlyer. She said that the SWISS issues had been fixed but were still in the "test" phase and thus hadn't been released online.
Imagine that...less than 24 hours after my article and the SWISS issue is resolved!!
Of course she spelled our last names incorrectly, so I am now on hold to resolve that issue. Nevertheless, hopefully this is good news!!!
