I'm terribly sorry for your illness and the terrible timing thereof. Glad that you've recovered.

I really couldn't agree more with orlandodlplat though. Somebody, be it you or somebody at BA, should have made sure you didn't get on the second flight. You found out later how contagious whatever you had is, likely norovirus, and you likely spread it to many others onboard.

Also, Happy Birthday. Glad you did something nice to celebrate. I'm many years younger and already seem to have given up on mine.
