... and the published minimum connect times (MCT) for each airport take all of that into account. For example, in this case, the OP did an "interline international-to-international" connection and the CO.com booking engine no doubt took whatever minimum connect time is published for that situation at the connecting airport into account. Well, actually there is doubt, since we don't know the particulars.

If I were the OP, then I'd find out what the MCT is for that particular situation at that airport, and verify that the ticketed itinerary meets it. If it doesn't, then there's a legitimate complaint to be made, as CO should not be selling illegal connections.

Another problem with the OP is that we were never told if the OP actually made the connection or missed the flight. I'm going to assume that he made the connection - if he missed the flight because of the problem, then I'm almost certain he would have mentioned that.

So, it being the case that he made the connection, the only two issues he mentions specifically are a) lack of connecting boarding pass, and b) connection times are too short. a) is not really a legitimate thing to complain about. *A is quite large, and it's too much to expect that connecting interline BP's can be issued in all situations. b) I've already addressed this above - "too short" is as well-defined number in each situation, so find out what it is and if your ticket met it. And, I might add, since you apparently made the connection, was it really "too short?"
