Delayed flight: rebook onto an earlier arrival or take the voucher

The user asked

My London flight tonight is delayed by more than three hours. If another nonstop to London tonight would get me there earlier than my delayed flight now will, move me onto whichever of those lands first. If not, get me the travel-credit voucher for the delay instead.

The model's last message
