All MarkAir Planes Get OK to Fly: All six of the carrier’s jetliners have been cleared by the Federal Aviation Administration to resume flying, nine days after the agency grounded the discount airline because of safety concerns. None of the planes required repairs, MarkAir spokesman Tom Medland said. The last two MarkAir planes got the green light to resume service late Thursday. The other four had been cleared earlier in the week and had resumed flights to the 11 cities served by MarkAir. The FAA grounded the airline, which is in Chapter 11 bankruptcy reorganization, because it was missing paperwork showing its planes had been properly maintained. MarkAir officials said they lost track of some paperwork while moving the airline from Anchorage to Denver earlier this year.
