It would now appear that the morning flight VY9981 has been removed from the scedule from 14 May. Also my booking has been transferred to the late flight (without any communication advising or requesting this). This is after I made email enquiries with Vueling which they were prompt in answering and I give them credit for this. They had advised me that my flight was still confirmed as booked but that they didn't know what was happening either.
I have now requested a refund as the late flight is not an acceptable change.
