FYI - Air Canada has cancelled its flight schedule into POP until December of this year. This leaves us Canadians with West Jet as our only option unless we want to go via the USA.
Sign up for their newsletters if you haven't, we just got a 20%off discount code for being on their list and are travelling in October direct from Toronto for $460CAN with the code. Worth it! And they are involved in a few communities in DR, building schools etc. Great airline.
They have cancelled flights to POP until December. Look online, nothing is available. I also spoke with two agents yesterday morning before booking with West Jet.
