I did the same thing! My mom had booked the flights for us and I thought we were flying back on Friday. She had booked Thursday instead so when I called to check-in the flight had already left. The agent was really cagey about it too and didnβt outright tell me the flight left that day. Weird and expensive af and now Iβve got a lifelong complex.
Thatβs amazing and embarrassing haha
