Top tips for finding cheap flights to St. Maarten

You may want to fly with Delta Air Lines, as they typically pass out activity kits to younger children to ensure they have something to do on their flights.
  • It would be best if you arrived at the airport in Newark two to three hours early for an international flight to St. Maarten.

Flight was delayed before take off and at landing. Baggage took 20 minutes. Flight crew would not serve full soft drink and had to ask multiple times before receiving water.

On time! There were plenty of airport employees who were able to keep us moving in the right direction. The crew on the plane were professional.

I continue to be satisfied with Delta’s excellent service out of LGA. The digit id works well and gets me through security in no time. Whenever possible, I choose Delta.

Was revoked with Jet Blue due to delay from Kenya Air

WiFi didn’t work. Flight delayed 3 hours Crew members were illiterate Seat lean back did not work.

My flight yesterday evening was delayed 3.5 hours with no water or food service. Poor experience

Transparency from pilots, quick boarding and exiting the plane, staff greeted to each and everyone,

WiFi didn’t work most of the time. The usb chargers would work only occasionally for 5 mins and wouldn’t charge after that. Had to keep trying repeatedly at each of the seats in the row.

The crew bent over backwards to thank us for flying and make us comfortable. The food service was quick and efficient. The Captain communicated and said goodbye and thank you as we departed. They really stood out!

Flight delayed. Air broken. Cabin was hot enough to pass out. Delta shuttle’s becoming worse and worse.

Crew was amazing, takeoff wonderful. The bathroom was disgusting from before takeoff the odor made the flight uncomfortable as you could smell the bathroom from the center of the plane where we were sitting. Smelled like raw sewage. My daughter was throwing up as we landed due to the smell and horrible turbulence as we approached Newark.

I'm a United 1K member and have ben for 10 years. The gate agent had no control over the boarding process and had us passengers queued for hours as delays were announced. On the plane, the overhead air nozzle was broken so col over was powering through on me and the passenger next to me. Not a great experience for a million miler on United. Feel free to contact me. Josh Smigel - DM426089

Everything was the best it could be. Crew found me with pre- ordered food. Excellent experience!

Improve the food offerings and cabin seating. My wife would prefer to fly another airline, even with a connection for a more comfortable trip. A 737-8 should not be scheduled for a 6 hour segment, which turned into 7.5 hours due to the origin ground delay.

As I wrote earlier, poor planning and/or communication. At least twice, we were told that we would be boarding in less than ten minutes, only to have the flight again delayed at least another hour.

Cree was organized and pleasant. Plane had good seating but as it’s a shuttle toilets hadn’t been thoroughly cleaned (eg. bins too full)

All good flight was 35 minutes early when arriving in Edinburgh

Flight left on time, arrived early, pleasant staff provided water, coffee, etc. access to bathrooms was reasonable and were well maintained. blankets were available, lots of entertainment options. LUGGAGE SERVICE WAS GREAT. I got my one checked bag quickly and was able to make a bus connection for a 2 hour bus ride saving me from waiting another 1.5 hours.

They promise free wi-fi prior to boarding and then once on board you are informed you have to purchase wifi even after being a mileagePlus member.

Both our flights were delayed. Almost didn’t get in the second flight. Staff was rude to the bone.

Crew were professional and kind. The flight was smooth. But... The internet, which we paid 35 dollars for, did not work for most of the flight. This made providing media for our child an uncomfortable hassle.

Overall fine. Seemed like one of the older model planes? Crew was mostly very kind, though some of the female attendants were a rather abrupt during the food service.

Leave on time. We waited on the plane for hour hours and it was hot and smelly

The flight attendant on my side of business class seemed like a novice and did not provide good service. Otherwise the flight was good and the entertainment system was very good. No free WiFi.

Flying in the United States with the major airlines has become so underwhelming. A 2-3hr flight in most other parts of the world with the major carriers of the area comes with newer, CLEANER aircraft and significantly better in flight service in terms of both staff attitude and a actual meal service.

I am writing to share detailed feedback regarding my recent journey with American Airlines on the New York (JFK) to New Delhi (DEL) sector, which was ultimately diverted to Jaipur (JAI) due to weather conditions. At the outset, I would like to acknowledge that this was a full long-haul flight of approximately 14–15 hours, and while the journey fulfilled its primary transport objective, several aspects of the experience warrant both recognition and constructive feedback. 1. Cabin Crew Conduct and Service Consistency While the majority of the cabin crew maintained a polite and professional demeanor, one flight attendant’s conduct was notably inconsistent with expected service standards. The tone was often directive and lacked the warmth and guest-centric engagement typically associated with long-haul service. This created a perceptible imbalance in the cabin experience. Although other crew members acknowledged and apologized for the behavior, it highlighted a gap in service standardization and supervisory oversight. 2. Inflight Experience (IFE & Comfort) The inflight entertainment system was unreliable, with content failing to load consistently throughout the journey. Seating comfort in economy class was below expectations when compared with other international long-haul carriers. Cabin environment management at times felt unsettled, with noticeable noise and movement in the aisles. 3. Disruption Handling and Communication (DEL Diversion to JAI) The diversion to Jaipur due to weather was understandably beyond the airline’s control. However, the handling of post-diversion communication and guest management was an area of concern: Information during and after the diversion was fragmented and lacked clarity Limited guidance was provided upon disembarkation regarding next steps (transport, accommodation, onward travel) Ground coordination appeared inconsistent, with hotel partners and passengers receiving incomplete or delayed updates Communication the following morning remained unclear, including last-minute changes to transfer timings This resulted in avoidable uncertainty during a critical disruption phase. 4. Positive Acknowledgment – Ground Recovery Arrangements It is important to recognize that despite the initial communication gaps, the overall recovery framework was eventually well executed: Hotel accommodation was arranged efficiently Meal vouchers were provided appropriately Transfers between airport and hotel were organized in a structured manner Given the sudden and large-scale disruption, these arrangements were commendable and reflect the airline’s ability to operationally recover once systems were in place. 5. Recommendations for Improvement In the interest of strengthening the overall customer experience, I would respectfully propose the following: Service Delivery Reinforce consistent cabin crew service standards, particularly for long-haul sectors Enhance supervisory presence to address outlier behaviors in real time Inflight Product Improve reliability of inflight entertainment systems Reassess economy seating comfort for ultra-long-haul routes Disruption Management Establish a more visible “Care & Coordination Team” during irregular operations Ensure clear, centralized communication (single source of truth) for passengers and ground partners Provide structured briefing points to hotel and transport vendors to avoid information gaps Introduce proactive guest engagement (clear next steps, timelines, reassurance) Closing Reflection: While the journey was impacted by both controllable and uncontrollable factors, the overall experience would have been significantly enhanced through greater consistency in service delivery and more structured communication during disruption. I appreciate the efforts made by the broader team in arranging accommodation and onward logistics under challenging circumstances. With improved coordination and alignment, the experience can be elevated to match the expectations of a global long-haul carrier. Thank you for your attention to this feedback. I trust it will be received constructively and contribute to ongoing service improvement. Warm regards, Soosnata Chowdhury Convert effective for airlines) Or tailor tone

Wifi was spotty. Tray table was very dirty when I sat down.

Flight was extremely hot and they made us check our bags when the space was nowhere near full

Same plane as RDU to LGA — internet not working. Pilot issue of some sort at end of prior flight - I was on same plane for my connection. Late/delayed —

For an international flight the seats were smaller than most flight I have been on in economy. I don’t know the size of the seats or perhaps it was the size of the seat dividers that made the seats feel smaller and little amount of space to even turn your body if you needed to

Nice plane, clean, wifi available and movies. All the flight attendants were courteous.

First the flt was delayed over 2 hrs bc of plane mechanics that should have been handled better! No text or email was sent so only found out at the airport so there we sat for 5 hours! THATS RIDICULOUS! The gate area was filthy! No agents showed up till hr before so no additional info was given-waited online for 15 mins while the gate agent chatted and got together then given last seat in back of plane!! No priority for senior or anything-took attendants over 2hrs to serve drinks and snack-WHY are they not served together? By time snack came needed another drink! Worst service in my life!

All the TV screens in my rows was non functional . The map shown for an international route was antiqued..

Flight did not have onboard charging and TV screen flickering.

Boarding process was terrible. No assigned seat until the gate, then a long line to get seat assignment.

The space between seat rows seemed to be larger than other airlines. I didn’t check their food or entertainment since I slept most of the way. They do seem to have a lot of options for purchase though.

Kayak sucked. You gave me a confirmation number that was not useable by the jet blue system. Nor did you send any check in emails. I’ll not be using your site again. Nice work.

We were delayed and had to circle due to weather and had to divert for fuel. While I understand that you can’t control the weather I would have appreciated knowing that the crew wasn’t going to run out of hours and then having to spend the night in the Raleigh airport.

Automated scanning was slow and somewhat haphazard. Too many people were unfamiliar with the tech and were forced to learn on the fly. The hands off approach of the gate staff made it more uncomfortable. This needs work. Overall the flight and cabin crew were excellent.

Crew were fantastic and so catering and wonderful! Full score for the entire crew!

Awful. Not water, or chargers or space under the seats, the plane was very old and poor maintenance, seats really dirty, sticky, seats pockets with wires pinching your knees. Connection with no announcements, plane departed 1.30 hour earlier for an extra stop to refueling in Trinidad & Tobago. Even that we had a 3 hrs delay, seated in the plane in the runway.

Really bad. Uncommunicated stop in Trinidad & Tobago for refueling. Extra stop added 3 hours of discomfort without allowing off the seat. Not even water, or chargers or boarding groups.

Staff were unfriendly and rude. Was stuck on runway for 2 hours after arrival in Boston.

Horrible service. No communication from the crew as to why a 6 hour delay then cancellation

We waited in an overcrowded bus for over a half hour. It was uncomfortable. It would have been better to have waited in the terminal in a line

The food for sale on board has opportunity for improvement.

I paid extra for a comfortable seat in the second flight, but the plane didn't have those seats, the first one did

The Arajet person who greeted us initially was unhelpful & rude about the mandatory migration form which has to be completed digitally but the systems don’t work properly. The boarding gate was changed twice and initial boarding was delayed. Once on board we we had to wait an hour and a half before take off. It was hot and there was very little room for tall-ish people to fit their knees in. The crew were pleasant but working in a poor situation. The plane was delayed because we were waiting for people from a delayed interconnecting flight. Arajet must have known that before we were asked to board. Better information, decisions & communication were needed.

My seat was broken and the crew had to find me somewhere else to sit. The crew was extremely courteous about this
