Question on missing a leg

[Jimogr]

Ok, so it looks like the ash is on the way back.

I'm due to fly DUB-LHR-DEL on Monday with BA.

It looks like Irish airspace may close because of the ash.

I'm considering catching a ferry across to UK tomorrow to catch the main part of my flight LHR-DEL.

I've read in a number of places that if you do not turn up for the first leg of a journey the rest is cancelled. This seems to apply for a few airlines, but I cannot find the specific information for BA and cannot get through to their call center.

So it I skip DUB-LHR can I turn up in London and take LHR-DEL?

The booking was all made as one. The first leg is a BA codeshare.

Thanks.

Normally your second leg would be cancelled - however I would phone the airline in morning and explain you feel more comfortable with a backup plan - based on the latest info from NATS / Met Office I think they may well manually overwrite the rules.
