No boarding bridge this time — we walked out to a bus and climbed the stairs up to the aircraft. Not the most convenient, but we got lucky with clear, sunny weather, so it actually felt kind of nice to get some fresh air before boarding. No entertainment screens on board, which is pretty standard for a budget carrier, but I appreciated that each seat had two types of USB ports with fast charging — a small thing, but it kept my devices topped up for the whole flight. The cabin crew were the highlight. Genuinely warm, attentive, and professional throughout, which made a big difference on a longer short-haul flight like this. Overall, a comfortable four-hour flight for the price. No frills, but everything worked, and the crew's service made it feel better than a typical no-frills experience. **Pros: Friendly, professional crew; fast-charging USB ports; comfortable seating **Cons: No boarding bridge (bus + stairs); no in-flight entertainment

Flight delayed 3 HR 45 min, but prior notification given. However, plans had already affected.

They used the ATR 72-500 for the route and I love it.

Delayed 7 hours plus. Given $15 worth of meal at Subway but it was actually we can only choose 1 set meal instead of $15 of anything. The staff at subway weren’t happy to serve huge group of us. No detailed explanation given by the airline and we just have to keep looking for information at the departure tv screen.

Was all very easy, from buying the ticket online to walking stratup to the check-in desk, helpful and friendly checkin staff, punctual take off, good standard of aircraft, luggage was waiting by the time I had cleared immigration. Thumbs up all round.

No frills, basic flight in a puddle jumper. I wasn’t expecting refreshments nor entertainment. Everything was efficient, and everyone was pleasant.

The only problem was that I bought ticket on a third party app but I have to pay extra luggage cost, because of in their system different from my bought ticket. Every other was perfect

I don’t like the sour face of the check in staff at Penang international airport, front desk service provider should be more friendly n smiles always 😊

It was delayed for more than 1 hour due to LIMA when many planes landed & took-off at the same time. It could ve been better if the pilot or crew informed us every few minutes so that we know what’s going on.

Flights were delayed, Food was good but only 1 meal instead of 2.

We are row 11, when the crew came to us, only one meal choice was available.

Comfortable seats in economy, managed a few hours sleep in an o night flight but the food was terrible. Surprising as Malaysia airlines has been good in the past. Service was mediocre this time too.

Vast improvement needed in customer service. I couldn’t get the drink of my choice during both meals (i.e. sparking water and Diet Coke). I had used plastic cups falling onto me from the tray. No eye contact when they thank you on the way out signalling an insincere thank you.

The flight isn’t great, as the plane has faulty with light and noise. It blinks and make noise for 8hrs non stop! Causing health and sensory issues! Causing Hazard matter to all 3 babies that on bassinet seats. This matters affected 12 passengers and the most horrible flight I ever experience. Have been flying with MAS for more 30yrs and this is the worst! Very disappointed

AC not working, just slowly blowing room temperature air. Long taxi time does not help as well. Sweating all over the whole trip.

The IFE is quite unconvenient if using our own device. Not all passenger brought their own earphone/headphone.

Service / food has to be much better. Staff were not very attentive to requests. Requested for a second serve of coke and got a weird look back from the host! Was also told they don’t have extra water bottles when I requested for one before sleep! Dinner time food was very minimum and average.

Delayed, not enough information. Had to ask for refreshments, crew could have been more proactive

Delayed for 45 minutes. Don't know what's the issue. Other than that, food was not to my satisfaction. However it's okay.

You should have given upgrade at 50% off instead with half full flight on to the hot seat that is how you treat the guest by offering upgrade to the hot seat guest would be happy to pay with the disc given

Not even water is free on board. Very cheap airline!

Quick and easy, short flight , 30 minutes. Staff was friendly, no food or drinks in this very short flight.
