http://www.dailytelegraph.com.au/ne...rounded-airlines/story-e6freuy9-1226079506551 AIRLINES have learnt their lesson from last week's ash cloud debacle, embarking on a social media blitz to update passengers and limit chaotic scenes at airports. But, despite using Twitter, Facebook and text messages in a bid to avoid masses of unhappy travellers, phone lines went into meltdown as they struggled to keep up with passengers seeking information on the possible resumption of flights. Qantas, Virgin Australia, Jetstar and Tiger Airways were inundated with phone calls and questions on Twitter and Facebook. Passengers were being referred to airline websites for updates. Many vented anger about being on hold for up to three hours. Sydneysider David Miles tweeted: "Dear @JetstarNews @JetstarAirways - thank you for disconnecting me again. Have now wasted more than two hrs with you just to change a flight." Jetstar apologised on Twitter: "We are currently experiencing a high volume of calls due to the volcanic ash cloud - please be patient." Stephanie Rice and members of the Australian swimming team tweeted their return flight from the US was also delayed. "I'm in the worst mood ... flights been delayed 12hrs (just want to be home)," she tweeted. Qantas received some praise, with Lyndal Parker-Newlyn of Wollongong tweeting: "@QantasAirways have been careful and conservative and communicating on media and REALLY helpful on twitter. Gold star!" Virgin Australia customers made little complaint as the airline privately messaged them on Twitter. Tiger was the only airline not to use social media. Justin Browne summed up each airline's social media usage. "SM strategy of the airlines. @tigerairwaysaus 0 tweets @QantasMedia 4 tweets @VirginAustralia clear winners with a real person and lots of info."
