Good 6.3

Pros: We were able to fly standby on our original 2:30p flight but had to return to DCA for checked baggages later that day

Cons: Connecting flight from JFK to DCA was moved from approx 2:30p to nearly 8p, making our layover 7+ hours, as opposed to 1-2 hours. No reason for this change was provided. Delta crew member in JFK was rude and unhelpful. The second agent (who ultimately booked our standby tickets for our original connecting flight) was more pleasant.

Okay 5.0

Pros: Inflight experience was fine. TVs didn’t work but Flight attendants are friendly on Delta, cramped seating - but not unlike other airlines.

Cons: Regular fare seat assignment not available prior to gate . Airport concourse F - poor - limited services. Customer Service seemed uninterested and unable to provide service both on phone and at gate. I’m a frequent United flyer & today’s Delta service experience made me more loyal to UA.

Pros: No surprises. On time. Courteous. I suppose the most amazing thing is their app. It tells you when your bags get on! Also I forgot that I had a knife in my pocket. I ran back to the desk and she went back, found my bag, put the knife in there. Wow. What service. Also I notice that Atlanta is a lot nicer than it use to be. Attendants are more friendly and loading is more organized. Way to go Delta.

Excellent 9.0

Pros: Excellent service in most every respect! Boarding was easy, accommodations were quite ample, food was great, and the entertainment was plentiful.

Cons: Slight problem with making my seat into a bed, which wasn't fixable. Movies were good, except for the trailers before and after each, which seemed to take forever! Didn't get the seats my wife and originally booked with China Southern/Delta, but the substitution was quite adequate! Problems with checking in on flights, as neither airline seemed to be able to deal with this split ticket! But they tried very hard to make thing up to us, which goes a long way to making us feel like we are valued customers!

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.
