Air Canada Aeroplan won't open with Safari

Hi Mark --
It's opens fine for me. . .
If I were you, I would Reset Safari --
Using the first seven options. Uncheck the last three.

It could very well be a bad Cookie, clogged cache, etc.
Let us know how things are AFTER you restart Safari, OK?

Maybe the keychain has been corrupted.
It's weird that it would happen on two Macs, though.

Go into Applications> Utilities > Keychain Access.
Look for the Air Canada listing.
Delete it. Restart Safari, and try again.

I would also take Air Canada out of the Autofill listing in Safari Preferences> Autofill.

Try this, ok?

So go up to the Apple icon on the top left corner of your screen.
Double click and move your cursor down to "System Preferences."
Then go down to "Network."

Click on Advanced button down in the lower right.
In the resulting box, click on the top menu > DNS.

Then, write down the two (probably) addresses in the left pane (DNS Servers).
(This is in case this doesn't work, and you can simply put the old ones back in easily)

Then erase those old numbers and replace with 208.67.222.222 (top one)
and 208.67.220.220 (lower one). The order is just to make things clearer to you.
It really doesn't matter.

Then when the new numbers are in there, go down to the lower right corner of that pane,
and click the OK button.

Restart Safari, and test again.
Here's hoping . . .

Hi Mark

would you mind to explain the logic on this? and what DNS servers those are? ... will they stay in >the system when I use the wireless this server only? etc etc ...

will I need to be watching these DNS entries each time I connect to another wireless system?

well, the 'logic' is that sometimes yer isp and/or router are slow, inaccurate, hacked (rarely) or out of action - both in general, and sometimes for specific sites.

The numbers you used were from OpenDns.org who provide a free service available to anyone, and also offer extra features for money. fwiw, I prefer dns to say server not found when I type something wrongly, rather than go to OpenDns advertising, but hey, it's free and has some bells & whistles you don't get elsewhere.

Entered in System Preferences, yes - the dns servers will be used for as long as you use the same Network Location ( chosen in System Prefs, or via the Apple Menu - Location )- assuming they're available & operating. An isp might reject dns requests to their if you're not connected to their service, for example - and a US only dns server might understandably be a bit slower in some other part of the world. Opendns should be a similar speed, anywhere. If you suspect it's being a slowpoke - http://code.google.com/p/namebench/ will seemingly track down the fastest one from your location.

... I went to the IP of my wireless router and looked at the internet settings and note that the DNS settings there are 64.59.144.18 and .19 .... I put those in to the main network replacing the ones you gave me, and it also works ... with great connection ... sheesh ... I am thinking that the default of the DNS setup when I first connected to this wireless network uses the IP of the router to connect to the DNS which is in the software of the router, but really should be copying the DNS info over to my computer network software ... something like that .. I am on the right track?

Sounds like the router wasn't/isn't doing its job (esp given the speed increase), perhaps specifically had cached a duff entry (usually temporary), or since I gather that other sites worked fine, maybe your mac had cached a bad one for Air Canada ? (again, very temporary, in theory)
Ideally, the router should handle it all for you, and you can ignore the settings in System Prefs - but hey-ho, things happen.

Thanks so much, andy.
It was just a tad over my head 😉

Do you have to login to the site?
And use a password?


EDIT:
Is your wife's Mac on the same version OS and Safari?
Or Maybe your ISP is blocking it?
