No worries, so hard to find brides that went through WestJet! From when we secured pricing, our guests had 2 weeks (technically 3 but our agent wanted the additional week to sort things out). So we actually did the passport invitations and had those done in November one we were 100% sure on the location and just didn't put pricing in them. We created a website and put that in the invites and went live with it as soon as we got the pricing. Once we secured it we had all the invites ready to go and most people got them within 1-3 days of us securing pricing so they could maximize their time to get the $200 down. Anyone we knew wouldn't be getting the invite until the second week, we sent them the link to the website.
Yes Westjet gives people less time to get the deposit down, but I don't believe the other airlines give you that much time to pay the rest of the balance which i think is what people are more concerned with. I went to a destination wedding 2 years ago and they used Sunwing, basically they got pricing and the entire balance had to be in April 1st (We found out end of January/early February) so there was a big rush to get it all in even though we weren't going until end of November. The other thing to keep in mind with Westjet is that you do need to have a good rough idea of your numbers since they aren't a chartered airline. When we got our quote we had to have the approximate numbers of each location. We ended up having more people than we expected coming and ran out of Saskatoon seats so 6 of the guests are paying $300 more than everyone else because they were last to sign up...So my advice on that would be going with higher numbers if it could be a possibility but obviously not too crazy because when they price things out, they were average the price of all the numbers you give them.
If you are going to go with Westjet, you do have the time to start giving people a heads up on pricing and how quick the deposit will be needed so I wouldn't worry about that part. @Chawrela
