I would love to see a decoder ring so I could make an apples to apples comparison. Otherwise, I have to rely on the AA negotiations website.
Do you want that decoder ring sized for the ring finger or the pinkie?

It's really not that difficult if you look at "pure" flying--the time and air miles distance from one city to another.
1. Most of us are paid by the hour. The hour starts when the door closes and the brake is released at the departure gate. The hour ends when the brake is set and the door opens at the arrival gate. (Unfortunate what happened to the 777 at DFW the other day, but I digress.) There are other issues--such as, ATC holds, etc--but let's not quibble.
2. WN flight attendants are paid by the "trip." A "trip" is defined as the air miles from DAL to HOU--WN's original and only route in the good ole days. According to the website I used, that is 239 air miles. EXCUSE ME! Is that quibbling I hear over in the back corner of the room?
3. According to Continental's website, a flight from IAH to PHX takes approximately 2 hours, 45 minutes and is 1010 air miles. Let's assume that the time and distance from HOU to PHX is the same. So, on WN that would be 4.23 trips. I don't know, nor do I care, if they round up or down or pay the exact fraction of a trip. (OK. The next quibbler will be forcibly ejected from the room.)
4. A top of scale domestic AA f/a makes $46/hr (see point one for start/end of hour) base pay. I don't know what the WN "per trip" top of scale is, but if you multiplied that by 4.23 then divided by 2.75 hours, it converts to over $50/hr.
As I said there are other things that enter in, but this is the basic pay comparison. IIRC in their new contract, WN f/as get something for the time on the ground while they are cleaning the a/c--I don't think it is flight pay, but it's something. We do not get paid at AA for cleaning the a/c on through flights.
Any other questions? Ask your mother. It was her idea.
