A: Good morning, sir. How can I help you?
B: Yes, I've got a ticket to London for tomorrow morning and I wonder if I could change it for a flight in the evening
A: I'll see what I can do. Could I see your ticket and passport please?
B: Yes of course. Here you are
A: No problem. And what time do you want to leave?
B: I'd like to take the last flight, please
A: I'm afraid the last flight is fully booked, but we have a seat at 19:35
B: That's fine. Can I have a window seat please?
Wyjaśnienie:
If could I --> subject should be in front of a verb following an if clause, so the correct grammar is if I could
Could I to see --> to is not needed
I'd like take --> missing to
I'm afraid but the last flight --> doesn't make sense, should be either "I'm afraid the last flight" or "I'm sorry but I'm afraid the last flight"
on the 19.35 --> exact time should use the proposition at
Can I having --> modal verbs should be followed by base verbs, so Can I have
