No it's quite different (as others mentioned, fixed shell, etc). Quite a few threads available if you need details.

Not really. It's mostly a question of loads, some people received the offer on all aircraft types but you don't receive them every time.

Not particularly, the email is always sent at the same time (just after a week from the flight date). This being said, many people who have answered positively ended up getting their paid upgrade.
