Practically, no.
You'll have the days off, but no money. Your "take home pay" isnt enough to take you home.
CX staff travel s really expensive. Economy (the seats are dreadful) is around US$200 return, business is US$450 return. The standby system is notoriously inaccurate in its "forecasts" and you're bottom of the list.
Every pilot, flight attendant and staff member who joined before you will be on the standby list ahead of you. Dependants of staff members will be ahead of you. Wives, husbands, kids, the lot.
Flights are full. There is the "jumpseat" option, but that's only if the captain gives it to you ahead of all the other requests he has for the jumpseat. If its a training flight, no are available for request.
If you live anywhere other than SFO or LAX, factor in travel costs, Cathay has almost no reciprocity with other carriers.
You have to travel on a firm ticket. If you miss the the flight (stuck, bumped etc.) that's strike 1 of 2.
Go ahead, commute. Six months, tops, before it ges too much.
