Summer vacations, more than 300 weather-related flight cancellations, and the seemingly unending maze of construction work that forces road closures and diversions all combined to make Thursday the second-busiest day in the history of LaGuardia Airport, and snarled traffic so bad that passengers were forced to abandon their vehicles and walk to their terminals. Friday may prove even hairier, thanks to more flight disruptions on Thursday night, and the fact that today is another one of LaGuardia's 45 separate "peak travel days" the Port Authority has declared for this summer.

How can you prepare your soul for your flight out of LGA? Monitor wait times and traffic, give yourself a few more hours to get there, and take public transit.

Almost 90 percent of people traveling to and from LaGuardia take private cars, taxis, or shuttles; 30 million people flew through LaGuardia last year. The Q70 LaGuardia Link, which takes riders of the E/F/M/R and 7 lines to Terminals B, C, and D, is currently free through Monday, September 2.

But Danny Pearlstein of the Riders Alliance said that mass transit is all but pointless if people don't know about it, and if MTA bus riders have to sit in a sea of private vehicles once they get close to LaGuardia. He also recommended that the MTA make the M60 free to encourage more people to take mass transit from Manhattan to LGA.

"It would take a coordinated publicity campaign to get people onto those buses, and then once those buses are at the airport, they would have to be given priority," said Pearlstein.

That would mean putting in a bus lane, or on roads that have been narrowed to one lane, "have traffic agents move everyone else out of the way and put the buses first, and let all the other passengers and drivers see that," Pearlstein said. "Because there is a piece of this that is behavior change, but that change has to be driven by policy."

To that end: Where's Governor Andrew Cuomo? The governor announced the $8 billion LaGuardia renovation project in 2015. ("Governor Cuomo's vision to transform this facility into a state of the art airport is well on its way and we look forward to many more momentous milestones ahead," the executive director of the Port Authority said in June.) Construction on Cuomo's LGA AirTrain, which is supposed to connect Willets Point to the airport, won't start until sometime next year, and is expected to take around two years.

Meanwhile, work on the new Central Terminal Building at Terminal B and to move the airport 600 feet closer to the Grand Central Parkway, freeing up desperately needed space for planes to taxi, is expected to continue until 2022. Delta's work on its own terminal won't be done until 2025.

"There's a confluence of problems here. The Port Authority is running the airport, you have the DOT running the roads around it, and you have the MTA running public transportation. There needs to be more coordination," Pearlstein said.

"Given Governor Cuomo's leadership around the airport renovation...This is one of those instances where his vaunted micromanaging might be extremely helpful," Pearlstein added. "It's fine to put money in to renovate it, but this years-long process, where literally millions of people are still using the airport, requires its own set of plans and attention, just like with the L train. It needs mitigation during construction."

A spokesperson for the Governor's Office has not returned our request for comment. Nor has a spokesperson for the Port Authority. [Update: Governor Cuomo told WNYC on Friday afternoon that the traffic issues were an "unavoidable inconvenience."]

Correction: Initially we wrote that the LaGuardia construction would create more runway space, when in fact it will create more space for planes to taxi. The number of runways will remain the same, at two. Newark Airport, which services 46 million annual passengers, has three.
