First off....... In June 2022 Canada is still trying to flatten the curve. We had to wear masks for ~ 10 hours flying across the pond and listen to snarky comments from crew "cover your nose", while everyone went without a mask for the 1-2 hour plus meal service, absolutely ridiculous! I would recommend avoiding Canada until they understand that the world has moved on in the understanding of COVID-19 as an endemic virus. Second, all of the Air Canada flights were late or delayed due to low staffing. We were also left waiting on the tarmac for several hours due to problems with airport infrastructure, meaning-they could not find someone to extend the jetway to the plane, causing us to nearly miss our connection.... 45 minutes sitting 20 feet from the airport, major fail. Third, the Canadian officials were a bit cunty, I was very surprised, I traveled to Canada often prior to the pandemic and was always greeted with a smile and a laugh.... those days are over, or on hold while thy continue to battle the virus. On to the Middle East for more history. Cheers!

JetBlue lacks free food offerings on long flights, and even their more meal oriented boxes for purchase which "are available on flights longer than 4 hours" have not been available on the last 4 flights over 4 hours that I have flown with them
