Hi
Good morning! You've reached Alliance Airways Customer service, how may I help you?
Hi, I need to check on my seat assignment please.
For sure! Could you please let me know your last  name and the booking confirmation number?
should be under Smith and #5f6f3h
Thank you very much Smith, please give me a minute to proceed further.
okay
Thank you for staying connected, Smith! According to the booking confirmation number, I've seen that you've been assigned to seat number M67 which is middle seat. Is that fine for you or you'd like to change according to your convenience and availability?
Would it be possible to change it to window?
Sure, thing! Let me check if there's any window seat available on the flight for you.
sure
Good news! There's window seat PH4 available for you, will that be fine for you?
Yes, thank you.
You're welcome, is there anything else I could help you with?
