Would it not be more desireable to operate TIP with an A320 with a C cabin instead of an A319 with all Y or convertable C/Y seating?
I think it would, but fleet constraints mean it has to be a short haul config.
Perhaps it was more important to get something/anything going that provides good connections between TIP and EDI/GLA/ABZ. I've heard that there's a lot of business lately between those two countries...
