VS95 Aircraft Swap

Hi

I've noticed that the VS95 LHR-YVR rotation has been operated by a 333 in place of the usual 343 these past few days. Any particular reason for the aircraft switch? Were these flights scheduled as a 333 or was it a last minute switch ? Anyone think this might be a more permanent change to this flight? Just wondering as I'll be taking this flight in August and would sort of like to get the newer A333 instead of the ancient 343.

Any info would be much appreciated.

Thanks

Seatguru's showing it as an A343 tomorrow so if it turns out not to be it's an unscheduled change. I wouldn't get your hopes up.

What dates your flight. Apparently some are being swapped out for the 333.

It's not just the 95 that being swapped. The Washington is going on the 300 the 16/17 June. And the 400 tonight is also in the 300. Boston is scheduled on the 300 18/19 June.

Flight date is August 3rd, any idea if it will be swapped ?
