As a regular SLF I try to be as polite as possible with the CC, and I enjoy that most of them ( with regular US carrier exemptions) respond with the same friendliness.
But I also note that there is a distinct degradation in the last 5 years, especially in flights going/coming from Eastern Europe.
a) too much booze ( St. Pete C-lounge, starting heavy drinking at 5:30 am !)
b) no respect for CC announcements
c) getting up as soon as the main gear touches down
d) continuous use of the cell phones
e) disrespectful ( using a political correct word ) behaviour
On a recent flight we had to PAX connecting in FRA from St. Pete to
IAD. They refused to strap in and used the proximity of the cabin attendant who tried to close their belts to have their hands all over her. Then they tried to order to booze which was declined. They got up early and opened the bins while still on the runway. At parking position we were advised by the cockpit to stay in our seats for a short moment.
The door opened and some grim looking German border guard came in and escorted the unpleasant fellows handcuffed off the plane. They receveived a roaring applause ! CC told us that they would go nowwhere today.
