No doubt. [TANGENT]Just a couple of weeks ago Europe was hit with very dense fog, and the day before many airlines proactively cancelled some flights, including one I had to be on to get to a business meeting in Lyons. The later flight would have put me in too late for a dinner meeting, and the earlier one left LHR at 7-something AM, and would have nuked my day (and involved waking up at an ungodly hour). I called BA and asked if I could simply switch my itinerary to Geneva and I'd drive it from there (GVA has many more flights a day than LYS). The lady told me yes, I could change the outbound to GVA, but only onto a flight which had the same booking inventory as my original flight, and (here's the kicker) I could only change the outbound, not the return. Well of course I couldn't find a one-way car hire from GVA to LYS (I need an automatic--yes, yes, I know). In the end I had to take the later LYS flight and miss my client dinner, all because BA didn't want to simply put me on flights into and out of an alternate nearby airport around my original flight times (with my company paying for the petrol to drive me to and from Lyons). The service was exactly the opposite of what I've come to expect on domestic snafus at AA, where routing rules and fare restrictions quickly get jettisoned when someone is affected by weather. It was made doubly bad that the cancellation was proactive.[/TANGENT]
