Translation of Inlandsflug

Thanks for the message. I hope that your friend here in England will soon be feeling better. If you decide to come at another time, I would be very pleased to meet you here. You can sleep at my place.
I have sent you the translation a few hours ago. I guess it has just arrived. That is very responsible of you. I will have a look at it immediately. If you want to address somebody formally in the singular, you must use 'usted'.
It was a short but nice letter from you. I hope that you had a great vacation. I realize that I should practice at least half an hour a day. Vocabulix helps to learn Spanish vocabulary.
