VIRGIN Australia's switch to a new booking and check-in system resulted in longer queues for some flights at the weekend but the airline said overall it had run relatively smoothly.
The airline is still advising passengers to turn up for flights earlier than usual this week as staff use Sabre's global reservations system for the first time in real time.
Virgin spokeswoman Emma Copeman said passengers had experienced longer queues for some flights at airports such as Los Angeles due to the switchover but at other airports "we have had no queues".
"In Sydney, Brisbane and Perth, we have been seeing quicker check ins . . . because we have extra staff on. People are generally getting to the airport earlier," she said.
On Saturday, some passengers waited longer than usual at Melbourne Airport's international terminal.
The airline said about 89 per cent of flights were on time on Saturday, while by the time of going to press the figure for on-time performance stood above 90 per cent for Sunday.
The transition to a new reservations and check-in system was seen as a big test for both the airline and Sabre.
About half of Virgin's 8000-strong workforce has undergone training for the new system over the past year.
The airline had amassed a small army of computer experts and support staff at the weekend to cope with the change from the Accenture-owned Navitaire system, which is typically used by budget airlines.
The airline will book a one-off cost from implementing Sabre, which will be disclosed when it releases its half-year results next month.
It has not revealed the ongoing cost of the more expensive Sabre system, saying only that "there was no material difference" to using Navitaire.
Although the transition to the system had run smoothly by last night, some industry insiders expect it to encounter some teething problems in the longer term.
Virgin has said the new system will allow it to better link its services to alliance partners such as Etihad and Singapore Airlines, as well as making its flights more visible to travel agents around the world.
The change will also result in Virgin switching its flight code from DJ to VA.
Qantas also uses Sabre, while its budget offshoot, Jetstar, runs on a Navitaire system.
