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.

My flight from PEN-KUL was re-timed for two hours or so due to some technical issue. It was not conveyed accordingly by the staff. Info only received via fellow passenger who also mentioned about the possibility of changing flight but different airport SZB. Changing flight is not easy since everyone is fighting for available seat unsystematically. Anywhere, I and my wife managed to get seat for slightly earlier flight from the retimed one. The issue should be handled more professionally and systematically.

I was pretty sure my seat includes a meal. But I guess I was wrong because I wasn't served a meal on my flight with Batik Air from Kota Kinabalu to Kuala Lumpur. I was fortunate because the layover was more than an hour in Kuala Lumpur. Otherwise, I could have cause a delay to the connecting flight to Taiwan because my terminal to board the next flight is located at different building. I had to take a train to the satellite building. Overall, all is well.

Batik Air is racing to the bottom of the list with its consistent flight delays. Especially out of Malaysia. Shocking that they keep getting away with it without any form of punishment from the authorities. Also very inconsistent rules on cabin luggage.

Need to improve the availability of the food. Seems like everything sold out

Did not like that we were not informed about the 4 hour delay, crew not friendly, noone at terminals to consult with...all employees for Batrik were behind glass aftervgoing through security at the gate again. Why no agent at Gate H 10 to answer questions? And no apology. Updates would have eased anxiety. Boarding is disorderly also.

During this flight all the crew just focused on making money by selling food and drinks. There was only one washroom open. And it really smelled bad and wasn’t usable. Even to watch something onboard entertainment u have to rent headphones pathetic airline but only one with direct flight so pretty much the only option from Karachi to KL

Delayed for 3 hours, need to pay extra for drinking water.

The OD2204 KUL-LGK was delayed 40 minutes due to air-condition malfuntion, after inspection the technician give green light for the flight to go as usual but the air-condition is still not working properly, passengers complaining to the stewardess but they cannot do anything, I did tweet to @malindoair to complaint but no reply from them … hope this Batik Air is not having problem like Rayani Air and I do hope the management do respond to my complaint as well

Nasi lemak was horrible. Plain white rice, tasteless sambal, no cucumber, no kacang, no ikan bilis. And the chicken was colourless and tasteless, tasted like boiled chicken. Entertainment system didn't work at all.

The worst kind of budget airline. To be honest....the plane was not that bad. Would have been good to have some food choices and some water. What was by far the worse is the passengers/customers that this airline attracts. Coughing and spluttering all over one another with no masks. Just disgusting. Pay for a better carrier and get a better class of passenger.
