One of the issues I think is the way that we go about rejoining a trip. Example of a situation I faced:

It’s 11PM and you’re flight is heading to your 30 hour layover on a 4 leg day. You either A) extend. You’ll be tired and get in at 3-4am, and probably won’t be able to get to bed at a decent time to do the next days 5am report, but you get to spend that whole day not flying. Or B) don’t extend. Go to a hotel, only to be given a 10-12 hour layover and then a DH to rejoin you’re layover. Now having to get dressed and do something on what was suppose to essentially be a day of rest for you.

I found this situation in miserable. You don’t want to extend, but you reeallllllyyyy don’t want to have to deal with that DH on a day you should be relaxing...
