Terrible
Terrible, they write in the documents that they will send you information but they don't, and when you ask for it you have to fill in HUGE forms because they want you to get tired an quit. Plane almost always late or cancelled, always missing baggage and then you need them to send you the documents for dealing with this and then the circus starts. They do everything to not be held accountable by try to make you give up. It's hours of work to get some kind of compensation that other airlines gives you within minutes.
This is as close to criminal as yo can get. Avoid at all costs
