I do plan to post return flight to Canada experience information. I am currently still in Sxm.

Also, t ran into another Canadian couple who flew down Sept 30 on Sunwing.That flight was not direct because it stopped in Punta Cana. They told me their bags and all passengers bags when they arrived were x-rayed.
This was the same experience we had.

Upload the arrive can app so you are ready to return to Canafa.

Keep you posted.
