Nope, just focused them more on South America. Am I right in saying only BA routes to South America now are Buenos Aires, Rio and Sau Paulo? And only IB routes to NA are ORD, JFK, BOS and LAX? Obviously consolodations have been made there.
If you mean BA, it may happen when it has sufficient longhaul aircraft, at present, it doesn't, hence the use of some the LHR slots it inherited for Mediterranean holiday sun flights.
I find it unlikely BA are going to increase EI's TA schedule at the expense of their own, as opposed to reducing their SA offerings to suit IB, as has happened
Agreed, maybe
in addition if demand warrants it, i.e. there are sufficient numbers of connecting pax from UK airports served by EI from DUB, but not by BA from LHR.
