Yes I have. I fully agree with you that IB C/J has progressed enormously in the past couple of years, notably short haul. Y, however, is really pretty horrible (except flights operated by Air Nostrum, which are not as fabulous as before but remain much better than mainline IB). I want to clarify my point though - I did not mean to 'bash' any airline and suggest that any of them is 'the worst', but just that Skyteam, with its diversity is in my humble opinion consistently in the same league as the two other major alliances. Some of the airlines in ST, OW, *A are good/bad for short haul/long haul Y/J/F and I just disagreed with the starting suggestion here that ST gets the worst of everything. Like you, I'd choose IB short-haul J over BA short-haul J in the same way I'd choose SU short-haul Y over AF short-haul Y and TK long-haul Y over LH long-haul Y.
