Just noticed this post. I just booked a qualifying PE return fare for the end of Sept to use with a companion flight, and it was £1,082.60 for my flight and £133.20 tax and surcharge for the companion flight, so a total of £1,215.80 for both flights, which is a pretty good deal for PE.patdavies said:Companion tickets with Virgin are only worth using with the lowest qualifying PE fare.
To use in UC, means that you have to buy a J class (full-price) UC ticket. It is cheaper to ignore the companion voucher and get 2 x Z class (cheapest) UC ticket.
Similarly with Economy.
Also companion flights travel on the same ticket classes as reward flights. These are very limited and need to be booked very early.
