Just saw that my LH flight from FRA-GRU today has been downgraded from a 747-8 to a 747-400 (Dec 16). I'd booked in J and had a confirmed points upgrade to F and have now been rebooked in J. I'm traveling AMS-FRA-GRU-SCL (single ticket, LH issued) and seems like slim pickings for alternate routings/options in F. Not sure how helpful staff will be at an outstation like AMS. Any suggestions on what I should expect? Am I still eligible for EU downgrade compensation given that I'd used points to upgrade to F? Zero communication from LH and I happened to notice the change on my own. I'd much prefer to fly in F than get any downgrade compensation, but don't see anything in the way of alternate routings.
