Correção de texto "Going to Travel"

Olá pessoal, estou começando a estudar por conta e pretendo fazer uma série de textos para obtenção de um vocabulário maior. Então agradeço desde já a todos que se disponibilizarem a corrigir!

Going to Travel

It was 5:45 in the morning when I woke up, brushed my teeth, I took a shower, made a coffee and I went to the airport. Getting there at 6:30a.m. I was waiting in the departure lounge. I already bought my airline tickets 10 days ago. When suddenly the airport agent communicates us that the departures are delayed. So, I had to wait for two hours to finally board the plane. I was exhausted and bothered for the delay, but it's alright, I know that unforeseen events. Now I'm going to visit my sister, she lives in Chicago and it's 10 hours of travel. I just want to relax and enjoy my trip.

Bom, apenas fui inventando e provavelmente deve haver erros hehehe
Se puderem me mostrar onde está errado e pelo o que eu poderia trocar,fico muito grato!

E uma pergunta. A expressão "unforeseen events" como "imprevistos acontecem" está aplicada corretamente?
