First of all, there may be a question mark whether Airflop can raise the GBP 300 million to purchase Aer Lingus.
Second, taking into account Airflop's horrendous customer relations record and certainly it's questionable safety record, would we really want to fly on Ruski Lingus.
Third, they may just want to pick up the Shannon base, repaint the planes in white with blue stripes with the Russian flag on the tail, and use Shannon as a jumping off point for the Americas, and run cheapie flights to tthe continent.
Not a bad business practice, but somehow the name "Aeroflot", in my opinion, does not mix nicely with customer confidence.
