Double/Triple/Quadruple staff levels for what? 15 minutes.
Without giving too information, a certain airline started flying from a certain airport, and higher staffing at security for that specific flight due to the workload involved, these staff are in for several hours as a result, often with little to do, and even the amount of staff hired in is minimal.
I can't see US officials will be spending hours doing nothing, my guess would be that they'll keep staffing levels low in order to keep the operation efficent, this may result in some delays at immigration though, possibly longer than they would be at BOS/JFK at the same time.
