IB + snow
Iberia's main hub in MAD sees it's fair share of snow/ice in Jan/Feb so the crew should be familiar. I've flown several times from MAD with IB and been de-iced.
While I applaud the commradship of informing a neighbouring plane of what you can see I do think we must remember that all companies have cowboys if you think you firm doesn't think again!! It's a little unfair to cruzify IB for the actions of one captain. Furthermore there are probably limited Spanish crew reading this thread so v little chance of defence!
