There are no direct flights to Regina from Vancouver tonight.
I have information that is enough to know that one of the tasks in Regina is expected to take place sometime around noon, or thereabouts. I hesitate to divulge where or what until it's happening to avoid completely spoiling Regina any more than it already is. Just trust me.
The teams will have to fly either through Edmonton or Calgary to get to Regina.
If by Edmonton, they have the following options from Vancouver:
17:05 Air Canada AC244 Edmonton (YEG) Arrival 19:34
20:10 Air Canada AC246 Edmonton (YEG) Arrival 22:40
21:20 Air Canada AC248 Edmonton (YEG) Arrival 23:49
23:10 Air Canada AC252 Edmonton (YEG) Arrival 01:39
However, no matter which flight they take to Edmonton, they are there over night. Next available flight to Regina:
May-13 Air Canada 8470 Regina 06:05 Arrival 07:43
If by Calgary, the following options are available from Vancouver:
17:00 Air Canada AC222 Calgary (YYC) Arrival 19:25
18:00 Air Canada AC224 Calgary (YYC) Arrival 20:25
19:30 Air Canada AC226 Calgary (YYC) Arrival 21:56
21:30 Air Canada AC228 Calgary (YYC) Arrival 23:56
23:10 Air Canada AC230 Calgary (YYC) Arrival 01:35
They will miss the 19:00 flight to Regina. Next flight from Calgary to Regina is:
AC8430 Regina A14 07:00 Arrival 08:25
There is, however, one more distinct possibility that ties into the task that is not expected to be visited until around noon.
AC8592 Saskatoon A27 23:30 Arrival 12:35
20:45 Air Canada AC8576 Saskatoon (YXE) Arrival 23:40
Perfect time to have an Hours of Operation stayover, and to have the teams drive from Saskatoon to Regina (2.5 hours roughly). Just in time to be expected at the task. Though this last bit is complete pure and utter speculation. And possibly wishful thinking on my part that they would be here in Saskatoon. But at least I can eliminate this particular avenue of speculation myself in a few hours. Plus, there are two places I can think of that an hours of operation would make sense. I won't name them here, but they are both immensely important in regards to the history of the area, and the history of Canada. One is just outside Saskatoon, the other is about an hours drive.
As a side note. I kinda went through this with the idea that teams are wanting the FASTEST flights with the shortest layovers possible. It's why I left out any flights arriving in Saskatoon tomorrow morning (beyond direct interference by producers telling teams which flights they cannot take, there is no reason why, if they have to go to Saskatoon first, they won't take one of those two available flights).
