Yes, I am.
Yes, I am Joe Baker.
Yes, I am. You must be Mr. Zhang Wei.
Did you have a good trip?/How was your flight?/Was it comfortable?
Yes, it was very pleasant.
Yes, it was enjoyable, thanks.
On the whole, not too bad. It was very pleasant!
It was quite good. But it was awfully long.
I just feel a little tired.
We were delayed taking off, and we encountered a lot of bad weather.
It was a bit turbulent.
Let me help you with your luggage.
Thank you very much.
No thanks. I can manage it.
