TXL-SFO Fare Help
I am having trouble booking a fare from TXL-SFO. I see pricing of ~$800 all-in on Orbitz, ITA, but neither allow me to book. Dates are Dec 17th outbound and return on Jan 6th. Fare booking class comes up as WMNN94W. Maybe there's a mistake in the system as far as this fare's seat availability? Thanks for any help people can shed on this.
