New to Lufthansa/Star Alliance. Traveling in C class today from JFK-FRA on LH 401. Wanted to access seat maps but only ways I know i.e. Orbitz/Expedia are not showing flight availability so cannot access the seat map. Is there another web portal I could use? Want to see if the 747 is configured for new business class tonight. Anyone know if LH 401 is sold out in business tonight?
