You and your friend booked two theater tickets in advance. Apology to your friend as you can't make it to the theater with him.
In the letter, you should:
·explain what reasons you can't make it
·give options what can be done with the ticket.
flight tickets cancelling
I'm sending this message to inform that I won't be able to join you at the theater on Friday night.
I'm sorry that I have to cancel our plan this weekend due to an urgent situation. My boss has assigned me to go on a business trip on the same day in Danang because the junior employees are not qualified to handle this job. This deal is extremely important to the company and my career as my boss guaranteed a big promotion if I could seal the business.
I know that you have planned this night for months and you really want us to be in the movie premiere together. However, since this trip determines my future, I'd have to skip this time.
If you accept, I'd like to give my ticket to Tim, a friend of mine. This guy is hilarious and easy-going. I believe you'll have an amazing time hanging out with him.
Again, I deeply apologize that I can't go this Friday and hope that you understand.
Please give me a call if you want to re-arrange my ticket to someone else.
