One piece of advice, though, is blow that Avios balance before April 28th. Those points are devaluing, particularly for use on BA's one world partners. For example, going from YVR-HKG in J on CX currently costs 60k points one-way. That's jumping to 90k points after the devaluation.

The points will still be useful for short flights (e.g. YVR - LAX), but since you have so many I'd consider a bigger trip.

How'd you get that balance? If it's from spending on the RBC BA card, you may have earned a companion certificate. Do some googling on how that works.
