Vuelo
If you are sitting in the front 4 seats which you may have paid extra for there should never be any occasion that you will be required to move. Even if the aircraft was empty but for you.
For your information Bays 1-4 are included in the same trim area so in the unlikely event of someone needing to be moved bays 3-4 should go back before paying customers. I hope you don't you pay to pre book a standard seat.
As for the only other option you've answered that one. Take the bus or train either would be full of alcoholic students scoffing 'donalds. Before anyone complains I have been guilty of that!
I am with MOL on this one and only this one, if you have a problem then go somewhere else
Anne Insider please walk in future.
