Just FYI, the "proper transportation" is the exact same thing, you just pay the airline $100 (in Delta's case, $150 per way) for the pleasure. They still go in

Just FYI, the "proper transportation" is the exact same thing, you just pay the airline $100 (in Delta's case, $150 per way) for the pleasure. They still go in the cabin with you, you still have all the same issues, they just want to skim some extra cash out of you. It wouldn't be nearly as irritating that they charge for it if there were something they were actually providing (like a more pet-friendly place to ride), but they don't.
