Plane broke down on tarmac (United) Going to try AA now. Won't arrive Cancun Till 7pm now.... crap...
I have a fear of this happening, which is why I always get trip insurance! I have no problem if there's a problem getting back to the UK though and I have to spend extra time in Cancun!
Think of it this way... It's always better if the plane breaks when it's on the ground. This is but a small roadbump. you'll be there in no time!
