what do you mean if I actually arrive?!
BA cancelled all domestic flights in and out of Heathrow the last three days; fewer landing slots available due to poor visibility, and many of their aircraft aren't equipped with cat.3 autoland; Sadly, BA, which was once Britain's national airline, is now perceived as a bit of a joke due to its poor reliability, with frequent cancellations due to fog or industrial disputes. When I flew to Bristol on Easyjet in November on a foggy day, almost every BA flight was cancelled or diverted while the low cost airlines such as Easyjet and Ryanair kept flying as normal.
