Travellers planning to fly out of Sydney Airport in the forseeable future have been warned to expect lengthy waits, after huge queues of people snaked out of the domestic terminal T2 on Monday morning.
The queues - made up of people waiting to check in, and those in the baggage claim area - have been attributed to enhanced security measures, after an alleged plot to bring down a flight was uncovered at the weekend.

Domestic terminal T2, which handles Jetstar, Virgin and Tiger flights, was the worst-affected with a long line of passengers extending out the door and along the footpath.

At one point the queue was so long there was "not enough pavement for everyone", one traveller said, and confusion reigned as passengers were unsure of which line to join.
Most flights were leaving on time despite the length of time it was taking to check passengers in, and the lines had largely cleared by midday.
Passengers for domestic flights have been advised to check in two hours before the plane's scheduled departure as the new security measures continue.
Jetstar sent a text message to passengers on Sunday night to warn them to leave "ample time for screening".
"The Australian Government has introduced additional aviation security measures at international and domestic terminals at Australia's major airports," the message said.
"Passengers should arrive at the airport two hours before domestic flights and three hours before international flights."
Passenger Sally Rugg estimated on Twitter that the check-in process would take at least an hour, with staff handing out water bottles to travellers.

Some passengers could see the lighter side of the situation, urging entrepreneurial cafe owners to deliver orders to the people queuing up.
Sydney Airport is understood to have put on extra staff to manage the increase in security measures. Security was beefed up late last week after authorities became aware of an alleged plot to blow up a flight bound from Sydney to the Middle East.
Four men were taken into custody in a series of arrests across Sydney on Saturday.
Air travellers have been warned they will need to be patient and limit both carry-on and checked-in luggage due to extra screening measures.

Transport minister Darren Chester apologised for the delays, urging all travellers to treat airport staff with respect despite understandable frustrations.
"There will be some queuing, and we apologise for that, but again, we can make no apology for the fact that we've made safety our number one priority," Mr Chester said on Monday.
"People should go about their business travel and leisure travel just like they would any other day, but recognise they may have to get to the airport just a bit earlier."
Mr Chester said the enhanced screening measures would be in place for as long as deemed necessary.
"These new provisions will be in place for as long as the security agencies advise us that that's the most appropriate course of action," he said.
Border Security Minister Peter Dutton urged passengers to be patient and avoid passing through security if it was not necessary.
"If you don't need to go inside the airport through the security section, then please don't," he told 9 News on Monday.
Sydney Airport has been contacted for comment.
