Virgin Blue said on Monday that it has restored its check-in system that crashed yesterday as the airline continues to grapple in restoring normalcy on its service flights across Australia and catch up on the backlogs left by the apparent computer glitch.

Company representative Colin Lippiatt admitted that despite the recovery of its system, Virgin Blue passengers would still encounter flight delays as he advised prospective travellers to first check Virgin's website to determine in advance if their flights were to proceed or cancelled.

Mr Lippiatt told ABC that the company hopes to clear the backlogs by the end of the day as he asked for patience on the unintended disruptions brought about by the system crash, at the same time requesting people to hold off non-essential travels with pledges that future flight credits would be given to those affected.

Virgin Blue said that the company is working overtime to assist stranded passengers as it ordered staffs to hand out pizzas and bottled to travellers while overnight accommodations were given to those trapped outside of their home bases.

The company reported that up to 100,000 passengers across the nation were stranded by the meltdown of its reservations and check-in systems that forced Virgin Blue to revert back into the arduous task of manual check-in arrangements.

Much of the travellers affected by the glitch complained of the absence of updates that they expected to be dispensed by Virgin Blue staff though a number of passengers were a bit forgiving as they conceded that incident was indeed unfortunate but the company staff could not be fully blamed for all the delays.

As of 1145 AEST on Monday, some passengers were still waiting for the resumption of their delayed flights in Darwin while an AAP report has stated that it has been told by a Virgin Blue spokeswoman that the airline's Brisbane and Perth flights already resumed scheduled services, also noting that Perth services were starting to clear backlogs created by the delays.
