Our trip out to Japan in late Feb also had the flights cancelled - we were flying F out J back, they offered us J both ways but my other half wants to fly F as it's a big anniversary trip. We rebooked JAL first out, and due to 'losing' a day in Japan if we take the offered BA morning flight home booked finnair J as the times work better. We've never flown JAL or finnair so it'll be interesting. My decision was also prompted by reading about the brunch menu on BA morning flights which sounds pretty poor for flights of that length...
