And I think that's a delusional dream.

If you had no prior bias/experience then the learning curve is not all that significant here. The basic process - put in airports and dates and buy flights - is trivial to "learn" and really not much different from most other OTAs or airlines.

The "hard" parts are advanced features which are now performed differently from the old site. Some of those are likely on purpose and some are likely not. But it is a far cry from the "nothing works OMFG it is awful I cannot do business with this company" rants coming up in this thread. For the vast majority of customers (and revenue) the site is working just fine. Whether we like it or not.
Of course you did. Because most of these things are relatively easy to set/change. Just means looking for what it was and remembering how it was set whenever ago.
