Top tips for finding a cheap flight out of the United Kingdom

  • Australia receives flights from the UK at many of its larger international airports, which also provide good onward connections to regional and domestic airports. For destinations in Western Australia, Perth Airport (PER) is the best airport to fly into. Brisbane Airport (BNE) and Sydney Airport (SYD) are on the east coast, while Melbourne Airport (MEL) and Adelaide Airport (ADL) are in the south east, so consider which one of these makes most sense depending on where your holiday will start. Cairns Airport (CNS) is in the north-east of the country and is a good option from the UK if you want to explore the very north of Queensland, while Darwin International Airport (DRW) services the Northern Territory.
  • If you are looking at flights to Australia so you can visit Kakadu National Park – a World Heritage site – think about flying into Darwin. This is the closest airport to Kakadu National Park and from here, you can complete your journey with a 3h road trip.
  • It is easy to exchange money in Australia. There are foreign currency counters in all the main airports, and it is also possible to use ATMs to withdraw Australian currency for your trip – please note that some of the more remote towns may not have ATMs available.
  • If you are travelling to the centre of Australia to see Ayers Rock and the surrounding area, consider flying into Sydney from the UK and booking a connecting flight to Alice Springs Airport (ASP). A direct flight takes around 3h and from there, you will need to hire a car for the 5-6h drive to Ayers Rock.
  • If you are travelling with children under the age of 7 and hiring a car to drive to and from the airport, it is mandatory to use an age-appropriate child car seat when driving in Australia. You should be able to reserve a car seat from the car hire company before you arrive. If travelling by taxi, be aware that, with the exception of New South Wales, it is not mandatory to use such a seat in a taxi, as long as the child can sit on the lap of an adult passenger in the back seat. In New South Wales, it is mandatory for children who are under a year old to be secured in some form of child car seat in a taxi, so you may want to consider bringing your seat from home.

We were not given option for meals since they ran out of the other option but good thing the remaining options tasted great.

Food could have been better. Too many passengers getting up and down all the time.

It was very good experience on board to Sydney with SQ.

The food options and quality could use some more excitement and variety.

Overall, very good. The food was better than expected with the exception of the pork and potatoes dinner at the end of the flight. My family all selected that dish and did not set it. I tried a bite also and it was honestly terrible. Also, it would be helpful to know when the snacks in the back of the plane are available.

Everything was good except food , food choices was very less. Washrooms were closed.overall good experience.

On time boarding I would like to see ground hostess to help transit customers to direct them to the right terminal and boarding gate. Last night, all the transit customers on SQ484 arriving Singapore had to merry go round to look for terminal and boarding gate to board SQ128 transit to KL Malaysia. We went to Terminal 3 taking the Skytrain to T3 and back to T3 to get out to look for different Skytrain to T2. On arrival t2, we had to go round to ask which boarding gate to KL. We only had 5 minutes to make to the boarding time at 6:55pm but we already spent more than 30 minutes running around to find the boarding gate. We were late at the boarding gate.

The crew have great customer service but their economy seating isn’t the most comfortable for a 220lbs+ guy and the food wasn’t bad, but wasn’t exceptional, either.

This flight was 16 hours and they made it very tolerable. Seats were comfortable and the staff very accommodating. I had plenty of inflight entertainment. Food was very good.

Service excellent would chose Singapore airlines as my first choice

Overall was a good experience and this particular flight the crew were great too at least in business class. It’s not always the case with flydubai. Few things would make me think twice in the future on this route. 1. The arrival into T3 might sound good but it is a real pain as it takes almost 30 mins to get to terminal on the bus as the aircraft still park at T2. The bag takes even longer . If they just let us off at T2, I’d be home within 30 mins of walking off the plane. Instead it takes 1.5 hours. 2. Due to the timing, the very tiny lounge in Penang is so crowded because half the lounge is closed for Qatar crew. Hardly anywhere to sit. 3. Flydubai app and site has a long way to go and using it is very unpleasant.

Excellent comfort and entertainment. Service poor..Food average with little choice.

Comfort good. Service as usual poor. Cabin temperature as usual too cold, about 15 degrees

The plane seemed pretty old and the food was not good

Flight was delayed by and hour but were informed beforehand

Seat 💺 was all the way on last row. Food was okay .

everything was great. I don't use on-board entertainment at all (I just read or sleep), but I appreciate that I couldn't hear anyone else's!

We had to deboard using stairs. Why didnt you have the aero-bridge?

They were very pleasant and helpful. My husband and I were sitted apart. We asked if we could be seated together were told flight ws fuly booked but would try. After a while they were able to make it work we got seats together. Their food is good and attendents are very friendly/helpful.

Fresh energetic and friendly crew, great food, brand new plane and non stop entertainment

So so, crew was overly professional and lacks human touch. Equipment is very old, especially the HKG-PVG CX366 flight. That plane along with its decor must have twenty years of history, or at least I had that impression.

I have a Peanut Allergy and the Steward staff were very accommodating in ensuring my safety as my allergy is life threatening. Very professional and so vested in their profession.

very professional and very attentive to my Special Needs as I required a Wheel Chair and assistance to board

Crew was great. But a bit understaffed. The business class seat, etc were dated. But comfortable. Some legs had entertainment system from a decade ago. Selections were rather poor. Food was mediocre at best. Actually poor for business class standards. I liked the lounge in Hong Kong. Showers were great. Food was nice.

Very noisy and careless crew on this overnight flight. They should understand customers want to sleep

The economy seats are much indeed roomier. Meals needs improvement.

When comes to Taiwan airlines China airlines is the best rest are pure trash

Baggage delayed for 2 days and still chasing for reimbursement of basis items. Very horrible customer care service.

Horrible airline. Missed my baggage and don’t want to reimburse for the basis items. Pathetic customer service

Horrible. No good food. Baggage missed to onboard and came after a day. No support to compensate the delay. Customer care cannot see the status of the complaint. No reply of the email.

They didn't board by zones and it was a free for all. The 16 hour flight was the most excruciating experience of my life and the seats were TINY... with no leg space and my feet were swollen immediately. The food was so bad it was inedible.

My experience with Qatar airway was very unsatisfactory. They lost my child’s stroller and I was told they found it and will send it to the hotel which was a lie. I had to go back to the airport baggage claim and pick up myself after trying to contact them many times!. There was a lack professional and communication. I am very disappointed in Qatar airway and will not be recommending them to friends and family nor will I be flying with them in the future.

No difference between US airline and Qatar. Both cramp as many people. The airline seems to change planes without notice choice is seating when making reservations online doesn’t match the plane a passenger is on. Especially paying extra. Nothing special No different than US carriers.

Very unimpressed that I was dumped from the seat I had booked and paid for after check in. Apparently a family wanted to sit together, however as they all were adults I think they should have pre booked their seats like I did. I will be approaching Qatar for a refund. That and the dreadful state of the flooding toilets made me wonder how they managed to be voted the best airline. Not worth the money.

Delayed my flights and no communication. We end up spending 6 hrs in Doha. No food or any concern from the airline. Terrible

Wasn’t allowed to continue with the purchased tickets because I hadn’t been able to go on the first scheduled leg.

The rows of seats in economy class are seriously close to one another making eating and resting just about impossible - there is hardly any legroom. Anyone larger than average size would have an incredibly uncomfortable flight. I had to basically share my seat with the lady passenger next to me as she was too big to fit into her allotted seat.

Being a platinum member, no attention given. No towel or tissue provided.

Food was good, attendants were friendly. Seats were not comfortable. Did not receive any amenities such as eyemask or earplugs that would have helped sleep. Additionally a large group of passengers boarded very late into boarding and were a disruption for almost the whole flight. Flight attendants did their best but the kids were making so much noise, kicking seats, and half the time no adult was sat with them so they weren’t being managed.

I had first class service from them. A little late taking off, but no major problem

Super surprised with the entire experience. Business class is incredible. Flight attendants around the world could learn customer service from these people. Simply fabulous experience all the way around.

Pillow and blanket are dirty. My son got multiple bites during the flight

Flight was on time. My group paid for seat’s so that us four can be seated next to each other. We all got separated. We all got middle seats, which made it more difficult to be able to get up and stretch or use the restroom. We tried talking to the employees at China Eastern and they were of no help. We will not be taking this flight or recommend this route to others in the future. Also I will be contacting customer service on how I can get our money back for paying for assigned seats.

China eastern was fantastic. I had read so many bad reviews that had made me nervous. However, I found that the flight attendant’s, and customer service check in etc. etc. was excellent. I had no problems. I would fly with them again!

Excellent! I had read some negative reviews but I found out that it was not all was not true! The staff was courteous and helpful. The flight take off and landing was nice & easy. The food was good! I asked for a second and I got it easily and without an attitude! All was wonderful!

Excellent experience however older aeroplanes used by China Eastern Airlines.

The crew were excellent, service amazing, blankets and pillow good, cabin temperature perfect, the flight on time, food was unusual selection however plentiful, price for tickets unbeatable through Kayak. Older aeroplanes used by China Eastern was the only down side.

Delay in off-boarding due to customs at SFO... pilot announcement should have come earlier so passengers don't clog aisles.

Better good than most, if not all European airlines. If you’re stuck in an economy seat anyways, China Eastern is a good choice because of shorter flight time, being able to overfly Russia

The temperature of the plane cabin is too hot. Sweat and uncomfortable. Also my food tray was broken down drinks fall off
