Acabo de enviar esto a ticketmaster irlanda, a ver si contestan o me llaman.

"I'm planning to get on presale 4 tickets for the u2 homecoming but 2 of them are intended to be exchanged for 2 tickets for another tour stop.

My question is as follows:

If i do proceed to print out the 4 tickets purchased is it needed that the card holder shows up at the gate with the other ticket holders (holding the remaining 3 tickets paid by the card holder). I'd need help asap"
