When do I arrive ??
 

I am getting conflicting answers, so I am appealing to the experts:

If I leave YVR on Feb 26 AC 7, do I arrive in HKG on Feb 27th (my answer) or Feb 28th (AC answer)?

Thanks

The correct answer is departure date +2 so in your case Feb 28. Once you cross the dateline going West you lose a day. Coming back East bound you gain it back. So on the return, presuming you go east and not RTW, you'll arrive back the same day you left HKG. If you go West and travel continuously, you can make it back in Departure +1. No fun but doable.

....airline economics: The only industry where the value of a perishable goes up as the best before date approaches....

AC007 arrives the next day (Feb 27).

AC015 arrives 2 days later (Feb 28).

You're right; AC was wrong.

That is assuming you're leaving from YYZ. If you leave from YVR; both AC007 and AC015 arrive one day later (Feb 27) since AC015 leaves just after midnight YVR time.

If you depart on Feb 26 from YVR, you'll arrive in HKG on Feb 27.
On the return HKG-YVR, you should arrive on the same day.

Don't they both arrive +1 (from Vancouver)

Only AC 15 is +2 from YYZ:

Toronto to Hong Kong, China (HKG) 7805 mi
0915 1850+1 7 343 X1
Above flight Eff. 12/9
1045 2000+1 7 343 567
Above flight Disc. 12/7
2155 0725+2 15 343 Daily

Vancouver to Hong Kong, China (HKG) 6387 mi
0120 0725+1 15 343 Daily
1245 1850+1 7 343 Daily
Above flight Eff. 12/9
1355 2000+1 7 343 1567
Above flight Disc. 12/8

. . . although you should be at YVR before midnight for AC15 so it will be +2 in your head! http://www.flyertalk.com/forum/wink.gif

You guys are making this all way too complicated.

The real answer is "shortly after the plane lands."

Thanks for the help - I am trying to plan this trip for my parents and the dateline is really screwing me up.

The joys of travel!
