Despite fears that federal sequestration would lead to problems at the airports, a flight monitoring website reports that on-time performance of flights across the nation remains the same compared to a year ago, with said performance actually improving at LAX over the same time period. However, the effects of sequestration on TSA screening times are unknown as of yet, though officials are working to keep moving passengers through as quickly as possible. Yet, passenger complaints rose anyway during the same period, according to an academic report. Also, LAX Terminal 5 is getting $229 million in upgrades. Delta will fork over $12 million of that, mostly towards a new VIP lounge.
