Finally they have the tickets. It was quite complicated, Nina spent two hours on the phone with two clerks at Delta (one at a time) until they got it right. So Lena will go there on 2nd of october, and they all come here on 5th of november.
It's complicated because Lena needs a two way ticket, and they need one way, but as one way is somehow more expensive, it's two way for them too, except that Lena's return trip should be the same as their forward trip, on the same plane. Which somehow doesn't fit into the head of the average american dumbson, hurts between the ears. Hence two hours.
We can start preparing the house.
