hey,
a quick question
would be flying sq832 on 7 Aug.
found out that this flight was frequently switched between a 772 or 77w.
on sq website, if i tick "book with krisflyer miles" option, it is a 77w, without the tick, it shows 772,
http://flightaware.com/live/flight/SIA832, also indicated a mix of 772/77w.
sorry, i do not have other tools to verify, would like to understand if it is a norm that they frequently change the aircraft?
or it is a revonated J class for the 772?
Thanks
