Employee #1 April 9, 2013

Mr Torno, thank you so very much for the update! Clearly we are making some great progress with the planning. Seems when we get the approval, we’ll be ready to make a lot of implementations, which will put us ahead of other mergers. I’m excited about the endless possibilites this will bring for our great company...the NEW American!

Regards,

Mark

As has been our custom in the past, American, and now US Airways, wants to set the new standard for efficiency and execution. There is no doubt that we will become the world’s best airline very soon!

Mr. Torno, thank you very much for keeping us communicated in a clearly and amicable manner. In Mexico there are several stations where there are US and AA operations and we are more than willing to work hard and adapt any change for the wellbeing of our new AMERICAN

Day One, sounds far now but will arrive so fast! Oh, I’m sure it’s being strenous, but very exciting!

As for the system we will be using, as I said in a different blog I really fancy working with a new one, as it will be refreshing! And I also think operating with the new one, whichever it will be, and I want to make very clear this is my personal point of view, it is not a soley matter of American, if you take care of your job, learning is proactive. I never expect or wait to be teached


everything, time sometimes doesn’t allow it, but I don’t stop if I was not teached something, I am always clicking everywhere to know how it works and inquiring, even before my training starts, it is MY job, I need to master it. But again, it is my very personal point of view.

I will like to see everyone staring at American with wonder and regard of being the best airline… choiceless!

Thanks for mantaining us updated! May the best practices prevail and non existent better ones arise!

There are lots of big decisions ahead of us, and there are a lot of good people working on those choices. Whatever we decide will be the best solution for our customers, employees and airline. We are on the move!

Day One is a much anticipated day by employees and customers alike. We’ve all seen and know that “Change is a coming”. The key is to be open minded and receptive, from Management to agent. Then, within the blink of an eye we’ll be saying “Year One”. Thanks for all you do to keep us in the loop.

Change is certainly the news of the past year, and the wave of our future. This is all going to be hard work, but very gratifying work. I cannot imagine how much fun it will be working for the world’s biggest and best airline again.

Great update. I hope we look closely at the most recent merger with CO/UA and learn from the mistakes with their reservations system. I understand we want to move fast, but we all want the New American to make a great first impression. LOGO

We are looking very closely at previous mergers in order to gain learnings that will help us avoid mistakes, and improve our services. There are lots of examples that we looked at beginning last week. This type of review will continue as we roll towards Day One and beyond.

New American is here. As you said is not only to be bigger but to be better. I think we are already experiencing a better airline. Looking forward and working for “Day One”

We have created a great airline through our restructuring. With the merger we can create an even better airline with network scale and breadth that is the industry envy.

Employee #7 April 9, 2013

I believe we would all like to be “a part” of day one. As always and not only in the airline industry, change for some will be the most difficult part of our transition.

[Employee #7]

We are about to make aviation history with this change.

Employee #8 April 9, 2013

Thanks very much Mr Torno for sharing this Blog. I think always changes like this keep people expecting, expecting the best. This time is the same situation, we are expecting the Day One may means new prosedures, When I said “New” I mean improved. Because as you said, its not only about to be a great or big company. Its about to be a better one. Once again, thanks for sharing! LOGO
