I'm am going back to my place in Maho. I went down last month for a few weeks and posted a thread about it.

I'm going back tomorrow. This time flying Westjet. Last time Sunwing (Westjet was not flying to SXM at that point).
This time, during the check-in process to get my boarding pass, they now ask to scan in your QR vaccine information (Ontario, Canada).
Not a big deal if you have downloaded it already on your phone (some are still using the 2 printed cards).
It is a good idea to have a printed copy beside you so you can scan it.

Also, EHAS in SXM now wants the QR vaccine information uploaded when you get your QR pre-approval from them. I uploaded to EHAS and had my pre-approval for entry in 1 1/2 Hours.

That seems to be the only difference at this point.

That's all............keep you posted Dr Phjil SXM
