Hi Hiddy,
We are off to Argentina in late Sept (and then off to Panama in January). All thanks to IB's low fees!
Where we are, we have a choice of Glasgow or (slightly further) Edinburgh, or even Prestwick.
We tend to fly from Edinburgh now because of availability (and I like the public "lounger" seats where you can watch the aircraft) and on the outbound there is a good connection from LCY:

Via Heathrow, there is a flight we use that leaves a little earlier (I hate early mornings too!)

But it has a longer connection time in London.
My wife is Spanish and we always plan a night in Madrid anyway, so not too worried about missed connection. And the EDI-MAD is a RFS to save the UK APD
For the return, we fly Easyjet direct MAD - EDI since it leaves at 4pm and gets in at 18:10. With the BA LCY we would get in to LCY at 18:20-ish and then have to wait hours for the connection. With BA LHR, it is not much different.
Anyway, may pm you in a while about some tips for our trip.
