When my best mate was living in Las Vegas, a friend phoned one morning to ask if I knew Virgin were having a one-day sale to the US, all seats £50.
The website had crashed, and the phone no. was engaged for 10 minutes so I drove straight into town to the travel agent and said I'd have any seat from Heathrow to LA or Las Vegas, and any coming back. They were disappearing as she looked so she just grabbed the first ones she found
I got one to and one from LA, 11 days apart, then worked out the internal flights.
Then went home and phoned mate to tell him when I was going to visit - thankfully he was going to be at home
