After all these years, let’s see how many (forget the Amerijet and Spirit strikes) after EAL went on strike??? 24 years??? why the query? This topic has been covered over the years too. Clearly, based on the aircraft you've flown, assuming you are a line captain, you can't be a virgin at having less than desirables of any ilk in your right seat.

Anyway, regardless of who you are paired up with... Keep it professional, keep it safe and don’t compromise your position. At the end of the day, you it is not incumbent upon you to have a beer or dinner whilst on layovers with any undesirable, regardless of their ilk, you are paired with during your sequence.
