Excellent 10.0

Pros: The crew was very nice and helpful, I had a nice spot on the plane, and it went very smoothly, especially considering the circumstances. I was supposed to be flying to Seattle later on, but I had to change my flight last minute because of the virus. The whole Delta team was very understanding and considerate and it made the process much less stressful.

Cons: My flight was cancelled and rescheduled for a later time the day before and there was a lot of changing of gates and running around, but I understand that everything has been hectic and I don’t blame that on you, I know you’re all doing your best.

Pros: Crew was amazing before and after the flight! Delta really showed if the world isn’t doing well, that their staff will keep those problems outside the plane and keep everyone calm and safe. Thank you Delta!

Cons: Absolutely nothing. I’m going to join the miles points with Delta.

Excellent 9.0

Pros: Due to COVID 19 we got a 737-800 on a route that usually boasts nothing better than a 717 so everything about this flight was superior to normal runs.

Cons: I wish DL could find a way to better manage food and drinks during the COVID 19 restrictive era.

Mediocre 2.0

Pros: I have no kind words for United Airlines. They abandoned my entirely family (including 3 small children) and hundreds of other people in the Dominican Republic when COVID19 travel restrictions went into effect. While other airlines have been sending empty planes back to repatriate their customers, United canceled all return flights and left us to fend for ourselves. We're still stuck here and never had any help even rebooking with another airline. We've had to spend thousands of dollars to try to get out of here and back to the United States. We finally were able to secure seats on a Delta flight that leaves tomorrow. It's unbelievable that they did this to us and I can't begin to explain the stress this put on or family. All they needed to do was honor their agreement to return us home and decided to throw our lives into turmoil instead.

Cons: They could have done what they were supposed to and not abandon my family in the Dominican Republic to fend for ourselves and destroy us financially.

Excellent 9.0

Pros: This was my first flight in Polaris and I was very impressed. I had a window seat and the cabin is configured so that you do not have to climb over someone else to exit your seat. In some other business class cabins on other airlines this isn’t always the case. This reminded me of a BA first class cabin setup. Nice large TV screen and window locker to hold items you want to access during the flight and also a small locker with a water bottle, headphones etc. Food was good and there is an option of do not disturb that you can switch on from your seat. One passenger slept through this meal and the crew were able to reheat his meal. Final comment. I had a 70 minute layover between landing from Hamburg and leaving to the US. Heathrow is a big airport and on a previous flight with BA I have missed a connection with a 90 minute layover. However with United, it was very efficient. No time to visit the lounge but made it to the gate with approx 10 minutes to spare.

FAQs for booking Missouri to Sydney flights

How does KAYAK’s flight Price Forecast tool help me choose the right time to buy?
KAYAK’s flight Price Forecast tool uses historical data to determine whether the price for a given destination and date is likely to change within 7 days, so travelers know whether to wait or book now.
*
Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
