Travel Mix Up

So I was supposed to leave today for Sunnyvale. My Administrative assistance booked a flight with a layover so I called the travel agency myself to see if I could get a direct flight. After some time looking for flights the lady said she had something that flew out a few hours later so I took it. I waited a few hours and then I went online to check in. When I tried checking in the site said I couldn't check in until 24 hours before my flight. I thought something was messed up so I looked at my new itinerary. It said my flight was for tomorrow at 5 not today at five. So I called back and all flights were sold out. Pretty crappy since I was supposed to start tomorrow. So I told them to rebook my hotel and car for Monday instead of today. Hopefully my new boss understands the mix up. I don't really mind that much since it's another day I get to spend with Hayley.
