How timely! This thread is proof positive searching prior to posting can elicit very helpful info.

I came here today to ask specifically about pets in cabin on Delta. We have flown several times before with our small dog. I called Delta and she was so lax about the whole thing. She made a note of the pet reservation, asked the size of the carrier and his weight including the carrier. I asked if I pay now or at check in. She said at check in. I have no written confirmation of my pet's reservation which makes me a bit uncomfortable.

BTW, each airline apparently differs on the requirement of a health certificate. UA required one for travel from US to Canada, but when I asked the DL agent she said they don't. I do have proof of rabies for entry to Canada for customs purposes, which is required.

NWA charged $150 each way for in cabin pet. His fare was sometimes more than mine!

Anyway, does this process sound right for reserving an in cabin pet on Delta? When I questioned whether this was all I had to do, she acted like I was taking up all her time. I regretted saying NO to the request to complete a survey at the end of the call prior to speaking with the agent.

ETA: Well, I'm glad I went with my gut. I called Delta and they had NO record of my pet 'reservation'. It is now noted.
