If you think CX is bad, please consider that everywhere else has got worse as the low cost rot sets in globally. Just as CX has worsened (from what I read here), so have many jobs in Europe.
Many jobs in Europe for captains are LCC with high hours, four to five sectors in a day, time pressured turns (you simply won’t believe how everyone rushes around compared to long haul ops), scoffing your food during a short sector length before top of descent (there’s no time on the turn for a meal break!), five in a row of super early starts, flying with brand new FOs rushed through training, and ten hour days are the norm (without a break remember!).
It’s a young man’s game; very tiring mentally and physically. Many guys mid to late forties take part-time options to have more recovery time, but each day at work is still way more stressful than a long haul sector.
All this worsening of the job conditions and increase in hassle has occurred with little in the way of decent package improvements despite the huge increase in productivity over the years.
If you really must be back in Europe, maybe LCC is an option but proceed with your eyes wide open!
