I love United

We had a brief wait at the gate while handling some technical issues, but they kept the AC running and started the entertainment while we waited! Thanks, Delta!

I needed more leg room but was unable to arrange this when I bought the ticket through Orbitz. I was not happy with this, but the Frontier agent at check-in arranged for a bulkhead seat which made me very happy. Thank yoi.
