✈️ Flight Guide: West Palm Beach (PBI) → Islip (ISP)

May is an active month for events on both ends of the PBI to ISP route. Around Palm Beach International Airport (PBI), visitors can enjoy coastal spring events, waterfront dining festivals, farmers markets, and early-summer cultural programming in West Palm Beach and Palm Beach. On Long Island, May draws crowds gearing up for beach season, memorial tributes and regional food and wine events—weekends may feature farmers markets, brewery and vineyard openings, and small-town festivals in the Hamptons and Montauk area. Expect increased hotel and shuttle demand on Memorial Day weekend; book accommodations and transportation early for May festival dates.

The best time to fly from Palm Beach International Airport (PBI) to Long Island MacArthur Airport (ISP) in May is early in the month and on midweek days—Tuesdays and Wednesdays typically offer the best combination of lower fares and lighter airport traffic. Early morning departures minimize risk of Florida afternoon storms and can reduce the chance of missed connections. Avoid flying on Friday afternoons and late Sunday evenings around Memorial Day weekend when both PBI and ISP see peak leisure demand. If you have flexibility, book flights for the first or second week of May to capture lower prices and less crowded terminals.

Choosing between direct and connecting flights for the PBI to ISP route in May depends on your priorities. Direct flights, when available, reduce total travel time (usually under ~2 hours) and lower the risk of missed connections, which is valuable during busy Memorial Day periods. Connecting itineraries often cost less and provide more schedule flexibility, routing through hubs such as Charlotte or Philadelphia; however, connections increase total travel time and introduce additional risk for missed or delayed segments. For May travel, if convenience and minimal transit time matter more (for business or tight schedules), prioritize nonstop options. If cost savings are the main factor and you can tolerate longer travel time, consider well-timed connections with ample layover buffers.

Major carriers serving Palm Beach International Airport (PBI) include American Airlines, JetBlue and Delta, while Long Island MacArthur Airport (ISP) is served by a mix of regional and low-cost carriers depending on the season. In May, compare carriers on flight frequency, on-time records, baggage policies and seat comfort. Low-cost carriers may offer lower base fares but charge for carry-on or checked baggage, while legacy carriers often include more frequent schedule options and loyalty program benefits. For the PBI to ISP route, prioritize an airline with reliable on-time performance for May travel and factor in baggage fees and connection reliability to determine overall value.

May brings warm, humid conditions in South Florida and cool-to-mild spring weather on Long Island. Pack light clothing, sunscreen and swimwear for Palm Beach, and include a lightweight jacket or sweater for evenings and breezy coastal conditions on Long Island. Allow extra time for Memorial Day weekend travel—arrive at Palm Beach International Airport (PBI) 90–120 minutes before domestic flights and prebook rental cars or shuttles for arrivals at Long Island MacArthur Airport (ISP). Monitor weather forecasts; afternoon thunderstorms in Florida can cause short delays, so book early-morning flights where possible. Use TSA PreCheck if available to speed security lines at PBI and check ISP’s parking/ground-transport updates prior to arrival.

Nonstop flight time between Palm Beach International Airport (PBI) and Long Island MacArthur Airport (ISP) is commonly about 1 hour 50 minutes to 2 hours 15 minutes depending on routing and aircraft type.

In May, schedule frequency increases on weekends and around Memorial Day as leisure travel picks up. Early-morning departures (6–9 AM) generally see lighter delays; afternoons in Florida can have convective weather that occasionally produces short weather-related delays.
