Is AUTHOR wrong in the post ? POST : Hey there, this is my first time posting in this subreddit but I feel like it's kind of a good place for me to ask the question of am I the asshole.

So I'm going up to see my friend who lives across the country for a week in the spring. I have it set up to where departing I'm on an early morning flight and leaving in a late night flight. On the last day we are hanging out, he decided that he wanted to go to a concert that was a few hours away. I'm unable to attend this concert because I have a flight to catch. He insisted that I get dropped off at the airport almost six hours before my flight departs, and my reaction to that was filled with annoyance

I feel kind of guilty because it's not like I don't want him to see the concert, but at the same time I picked those flight times to essentially maximize the amount of time we can do stuff together. The tour with actually announced a few days ago, where this trip has been planned since November.

One of the extra things so that's causing me to feel annoyed is that he blames this on me because I apparently planned the trip way too early. I started saving up for the plane tickets and November and bought them on Christmas. The plane tickets are already doubled their price so I feel like I made a decent move buying them when I did.

This isn't something that's going to ruin our friendship or anyting, but am I an asshole for feeling annoyed about him doing this? Thank you
