Original flight was canceled & we received no notification... Not from either airline nor from kayak.com. We showed up early at the airport and were told we weren't anywhere in the system, and that flight didn't exist. American Airlines blamed British Airways, and vice versa, and both blamed us for buying through kayak. We were in lines for 2 hours just trying to get someone to own the problem. A BA rep finally walked us to the AA desk and got them to acknowledge that they needed to work the issue and get us home. They did get us onto the one other flight that they had that day, so we did finally get home, but it was not a good experience, and neither AA or BA expressed much regret. For the most part, they alternated between blaming the other carrier and blaming us for buying through kayak.com. We do know that we don't ever again plan to fly on BA or AA, or buy or tickets through kayak. It's not worth the risk of getting stuck in that situation again.

Unfriendly staff, the pilot never announced anything during the entire flight including we’re at altitude, what the weather was like at the destination how much time is left if we were ahead or behind schedule etc. Very funny gay gene flight crew.

Check in was not good. They told me I needed a QR code for my vaccine card and pcr test per emirates rules. I spoke with emirates and they said this was not necessary and it would be handled in Boston. The agent at check in would not check me in without the code. I had to pay $275 for another pcr in airport with a QR code. Guess what?? Emirates did NOT need it and I wasted $275 on a test. Horrible experience. They need to get with with their partner airline and know the rules.

This was the worst flight I’ve ever been on. The plane had no fans at each seat and it was extremely hot for 10 hours. Each seat was unbelievably small so it was impossible to reach on the ground to pick something up as needed. When the person in front of me reclined his seat, I couldn’t even use my tray table fully.
