Hello!

First of all, I'm sorry for the bad english, and I would like to thank you all for the great info that this board provides.

I'm brazilian and my wife works for an national airline company. Recently it was announced an interline zed agreement with Delta (Low Zed for spouses and parents) and I have some doubts on several details. Before this, let me explain my plans: I will speak at a congress in Lisbon, on january 12th, and I was hoping to use an zed ticket for this. As I'm departing from Brazil (GIG), I know that I must go first to ATL, DTW or JFK and only then take a flight to someplace in Europe. Now, the doubts:

1) Delta doesn't have any direct flight to Lisbon, but in the site there are plenty connections in CDG and AMS. These flights have a Delta code, but they all are operated by AirFrance or KLM. Can I take one of this flights, even though they are operated by AF or KLM?

2) In case of a "no" as answer for the first question, what is my best option? I imagine I could take the flight to someplace in Spain and go to Lisbon by train or bus. On the other hand, there are few flights from ATL to Spain. Is it possible to know if they normally are full in this time of the year?

These are my main questions by now. It seams to me that I must decide these before making any other plans or inquires.

Once more, thank you for the great info in the board and any help that you may give me.

Sincerely,
Paulo
