I am looking for flights with a lot of business class seats, not just looking for flights with current upgrade availability. There aren't any flights today that I can see with more than 1 or 2 bclass seats from Paris, Munich, Frankfurt, or Brussels. The business inventory has gone way down. One flight has a few business seats open but they are listed in the fare class as nonexistent, and agents say they are not there and advise me not to change.
