( CNN ) -- Want to read that e-book or play Candy Crush while taxiing to the runway ? Add Southwest Airlines to the list of U.S. airlines that have received Federal Aviation Administration approval to allow passengers to use many portable electronic devices in all phases of flight . Southwest Airlines ' move Wednesday came three weeks after the FAA announced the loosening of electronics rules aboard aircraft . Under the new rules , passengers may use certain electronic devices in `` airplane mode '' during taxiing , takeoff and landing . Each airline has to prove to the FAA that devices are safe to use in airplane mode on its aircraft . JetBlue Airways and Delta Air Lines moved quickly to get FAA approval to allow devices on board on November 1 . American Airlines implemented the policy change November 4 . United Airlines unveiled its policy change November 6 , and US Airways announced its change November 7 . Other airlines are moving to get FAA approval to allow greater electronic use . Virgin America said it hopes to allow devices in all phases of flight this month . `` We 're in the process of applying through the new process and hope to implement the changes as soon as possible , with the goal of having the change live in November -- in time for the holidays , '' Virgin America spokeswoman Abby Lunardini wrote in an e-mail . Spirit Airlines was less specific about its time frame . `` We are in the process of coordinating with the FAA . I do n't have a specific implementation date at this time , '' Spirit spokeswoman Misty Pinson wrote in an e-mail . With such a new policy , some confusion exists about what 's still permitted on board . US Airways reminded passengers of some restrictions that remain in place . The airline noted that the eased restrictions apply only to domestic flights flown by its `` mainline '' aircraft , which means partner airline flights ( such as US Airways Express flights ) are not included . Those airlines have to get their own FAA approval . Smartphones and other devices must be operated in airplane mode or with cellular services disabled . The new expanded use of electronics does not apply to making or taking calls , which are still prohibited in flight . Phone calls are not allowed after the main cabin door is closed or before a crew member makes an announcement allowing calls upon arrival , US Airways said . Customers should not use their devices during safety announcements . For takeoff and landing , laptops and other electronic devices that weigh more than 2 pounds must be secured in an overhead bin or under the seat in front of passengers . Some folks had a sense of humor about the device debate . Earlier this month , @ RealMediaMedusa tweeted that `` Portable Electronics on Airplanes policy too late for Alec Baldwin , '' referring to the 2011 incident in which the actor refused to turn off his electronic device at the gate and got booted from a flight .
US Airways is newest airline to ease electronics rules . United , JetBlue , US Airways , United have changed their policies . Cell phone calls are still not permitted after the aircraft door is closed .
