Translation of boycott in Spanish

In the end we went up to the tower. We have never climbed so steep stairs ever before and once up we were really afraid to go down. There were no safety installation at this tower.
I wish you would help me to improve my Spanish. I am studying law in Germany and I am trying to learn Spanish. I hope you can help me and I could help you to learn German. Have a great day.
We arrived at the airport two hours prior to our flight with no seat guaranteed. As these are local flights, the counters open just 1 hour before take-off. The alternative root would be by bus.
