Scheduling Aps - equipment changes?

[blu]

Do any of the scheduling aps advise when an aircraft substitution happens?
We paid for advanced seat selection (codeshared BA J 789) only to find a few weeks later an aircraft substitution happened & our 'good seats' were not so good. Obviously happens but is there an alert?

You can set an "Aircraft change alert" in Expert Flyer.

Before Expert Flyer, I used to check fairly often for important flights - perhaps weekly up to a fortnight out, then more often.

But even EF doesn't help with changes a few hours out if I'm if aloft without wifi...

What did you end up on instead of the 789?
