You know, Empress
does know it all, but we also know a little bit too.
If you look at a timetable (which, you should do before you post questions like this), you'll see:
Code:
Flight Frm Departs To Arrives Typ Meal Freq Begins Until OperatedBy
AC 51 YYZ 9:30pm DEL 9:00pm 343 .T.TFSS 03JUL04 30OCT04
AC 51 YYZ 9:30pm DEL 9:00pm 343 M.W.... 25OCT04 27OCT04
AC 54 YYZ 9:30pm DEL 10:15pm 343 MT...SS 31OCT04 02APR05
(Flight numbers change with
exclusive dates of operation)
and then in reverse order
Code:
Flight Frm Departs To Arrives Typ Meal Freq Begins Until OperatedBy
AC 52 DEL 11:30pm YYZ 5:30am 343 BL M.W.FSS 03JUL04 29OCT04
AC 52 DEL 11:30pm YYZ 5:30am 343 BL .T.T... 26OCT04 28OCT04
AC 55 DEL 0:30am YYZ 5:50am 343 BL MT...SS 31OCT04 02APR05
(The same holds true)
What's interesting is that AC changes the even/odd nature of the flight (different definition of East/West v. North/South)
