Input: Text: this is my first post in reddit, wohoo! well, a few weeks ago i went on a solo trip to the capital of a certain south american nation which just won a major soccer tournament... one month before that i bought airplane tickets online, but i guess i didn't really check the month for the return ticket, it should have been 7 (july) but somehow clicked on 8 and never checked. the total cost was about $320 for the round trip, a decent price.
when did i realize about my error? the night before the departure, when i had to check in online! so i had to take a cab to the airport by 10 pm, run to the counter, and ask for a solution, hoping that there was one, because i had to return and go back to work the next day. in the end i could change my ticket date... by paying 'only' $1015, 3 times the original round trip cost, and more than half of the entire expenses in my trip. to make matters worse, the new schedule made me leave 9 hours earlier, so i missed my last half day. most expensive mistake of my life, only told my best friend about it.

TIFU by buying airplane ticket for wrong month and had to pay $1000
