Good job! I've done the same thing twice myself - once on Southwest, the other I forget. Southwest def. gave me a round trip ticket. I think the other airline gave me a one-way. Either way, kudos!

I was an EMT at the time then too. Now I'm a (internal medicine) doc, but haven't forgotten the streets. But I've also had that situation too (wrong doc, wrong nurse, just me with the confidence and practical knowledge). Don't be afraid to use them, just tell them what you need done.
