Talking about SEN+. On a recent STR->FRA leg every pax on the manifest was either HON+ or SEN+. Given that this is a flight with about 0% O&D pax the has a connection flight explanation would make some sense. Or not, who knows

For those complaining about pax looking at the manifest, they sticked it on the wall so that everyone who was waiting near the door for all the other pax to find their seat had to see it..
