Aggravate me enough, and I'll just pay someone to avoid the headache. At least, I'll do that if it's an option.
I'll spare you the tedious details. The short version is that booking our tickets to Dublin online for our trip this June was giving me a headache. After much trying to get things how I wanted, I called American Express. I paid them a little more than I would have paid online, but a short call was all it took to get everything just the way I wanted.
I did try calling the airline directly, and I nearly lost my temper while talking to their computerized system. Note to the airlines: just because the computer has a voice, and I speak to it instead of pushing buttons on the phone, that's not the same as talking to a real human being.
So I called Amex, got a real human being and got the job done with a brief, polite conversation.
Good customer service. What a novel idea.
