  • In Washington DC, you can board your flight to Kathmandu at Dulles International Airport (IAD), Baltimore Washington International Thurgood Marshall Airport (BWI), or Ronald Reagan Washington National Airport (DCA).

  • If you want to pray or meditate privately before your flight from DCA, you're in luck because the airport has a chapel. The chapel is located on Concourse B's south end, opposite the Delta Airlines gates. The chapel is open to everyone and hosts clergy-led Protestant worship, Catholic masses, and Islamic prayers on a regular basis.
  • If you're traveling with a pet, you can let it relieve itself in one of DCA’s designated pet areas. The said areas are found near Door 1 in Terminal A, across from the South Metrorail Station entrance in Terminal B, and opposite the North Metrorail Station in Terminal C.
  • In Kathmandu, you’ll alight from your flight at Tribhuvan International Airport (KTM). If you’d like to catch your breath before leaving this airport, you can do so at its Executive Lounge.

we bought trip insurance from you and could not use it. 'underrated' only return 50 % of trip cost. my doctor told me i have stage 4 cancer and that I might not live till the end of the month..

Flight got canceled without any prior information and it caused lot of trouble

No entertainment u less you pay. Wish there were some free movies

Staff were friendly, and provided great service. The food was plentiful and delicious. Food could have been hotter.

I was traveling business purposes and I only had one carry on and a personal computer back pack . My carry on was 8.5 kg little more than allowable. At jfk airport check in they did not let me carry it . I was little disappointed.

More leg room and comfortable seats at least for long flights

The entertainment selections are amazing. But the live TV is sometimes spotty. If you’re going to have it, then have it. If you can’t make it consistent, then, perhaps it’s better not to have it. The crew are always cordial when approached, but they seem to do the minimum and sit around, talking to each other in the back of the plane during the flight. I realize that delays are not always predictable, but I missed my flight in Dubai because we left 90 minutes late from Washington. I will say that Emirates took very good care of me in Dubai. But I would rather not be delayed.

Probably the best flight I’ve ever been on. Emirates first class is leagues beyond British airways and Lufthansa’s.

Great flight. Comfortable seats, courteous service, and excellent selection for entertainment.

Serving food took so long . Almost time close to lend. Plus during landing air pressure in cabin cuss ear blocked took long time to unblock.

Operated by American Airlines. Very chaotic and the crew was bit rough responding any enquiries. Restricted leg space.. Qatar would have been better

Qatar airways from Doha to guangzhau was excellent big bird Boeing 777 more room and smoothly flight, I Love it

It was good no problems made it on time for the next flight overseas!

The made us waiting and held our passports and boarding pass making us miss our flights

Not impressed. Only allowed one carry on on such a long flight.

The flight was good but my neighbor had the vent open full power for the whole flight and because the air was blowing from the side instead of from the top and I got very cold and ended up with a sore throat.

Bad experience with the delay n long wait time for connecting flight after missing the connection flight from Doha.

Wore experience due to delay and took me 3 days to reach my destination.

All over with Qatar airlines my experience was really bad due to delays and then putting me on different airlines and after 8 hours of wait I had to listen to their is no plane to fly for another 24 hours. Wore experience ever.

Excellent will be flying again in May with Qatar. to Botswana.

Excellent service and comfort from the moment you check in. Flight crew is hyper focused on making passengers comfortable and at ease. It’s like a flying hotel!

Only chicken as a meat dish through out the flight

Nothing really was great as such. Seen other no name airlines perform better.

Quality of service on board was very inconsistent. FA service primarily seemed robotic and they barely engaged with passengers

I’m unclear why I had to pay extra for assigned seats as Turkish airlines did not honor the seating. We were placed across the aisle from each other on TK 34, and were seated behind one another on TK 694. Because my name was misspelled on e-ticket (Klawiter, instead of Klawitter) I could not log onto website to get the connection gate number in Istanbul. The monitors in the airport were a jumbled mess 1/2 Arabic and 1/2 English.

On line check in needs a lot of improvement. I tried and gave up.

Food not good, flight attendants not the best, not accommodating very ruff

the female flight attendant was racist towards me. I could tell she treated the two other passengers next to me with more softness.

Oh my god! For an13 hour flight they serve you food just one time. Also don’t be thirsty they give you a little small cup of soda to drink. They seem like their goal is to feed you one so they don’t have to be bothered with you. It quite surprise for such a long flight there are several times to eat at least three and the food was well lackluster. The food and lack of offering drinks which were always hot no ice provided.

We were traveling first class. Checkin counter lady and her manager, both were in bad mood and did not treat us well about checking in the handbag. The gate agent took care of it right away. I travel Turkish twice a year in first class. No one has ever refused to check in the hand bag. Not sure, why this agent and her manager refused. Everything else was excellent.

Indigo attempts to make you pay for a seat during check in. I opted to not do this. The result - they allotted me and my minor son seats apart. In the interest of making maximum money, they seem to have lost common sense too. Similarly, even during the flight, the crew are busy trying to serve food to those who’ve already paid for it. By the time they’re done, it’s time to land and no one else is able to get anything. Sadly this seems to be what makes them profitable, customers just need to bear with it till a better airline comes along.

As usual invariably delayed Lots of time in getting chkd in baggage

Staff needs to be trained in managing customers better. Indigo appears to be a low cost airlines in all aspects.

Flight was delayed and also lots of mosquitoes on the flight

Two times the gate was changed and flight got delayed

INDIGO Never On Time & Always Prefer to Shuttle Passengers Like shuttle Corks

I did not like the communication gap existing amongst the staff and the customer. My flight to Nagpur was delayed by two and half hours but it was informed to me on email ( not by W.A. or SMS) when I have already left my home in Baner area. I was painfully detained at airport with luggage when the gate no. 10 was changed to 5. I'll never recommend your flight to anybody.

Seats don't recline, no charging points. New aircraft and very clean. Crew should serve some water atleast.

Wife and I were seated in separate seats across the aisle

There was inordinate delay without any plausible reason. This has become a normal feature of Indigo now a days.

Communication was terrible. Flight was delayed for 4-5 hours in DC (on the front end, and also after we boarded, we had to get off - some issue with fueling the old plane correctly). There was little to no information on timing or what was happening. Once we reach Delhi airspace, apparently there was weather that caused us not to land - we were actually near the ground, saw the run way, and lifted back up to the sky after being sooo close. Then we circled for about 30 minutes, and they decided to go to Jaipur to land until the weather cleared and to refuel. Again, once we landed in Jaipur (wrong city), there was little to no information on timing or what was happening. Then we heard that the crew was reaching their 24 hours. We sat on the place, on the tarmac for another 3 HOURS, with no food and not enough water for everyone on the flight. Then, they kicked us off the plane with no plan, in the wrong city. We went thru customs, got our bags (thank goodness), and had to ask a bunch of staff what was happening and what to do. Eventually, their soltuion was to bus people back to Delhi (like 6 hours we were told) but not everyone would fit on the bus, and unknown timing on when it would leave. At this point it was 9PM (we were scheduled to arrive in Delhi at 11AM...). My husband and I decided to risk it and take a cab that we had to pay ourselves (about $200 US dollars) to get to Delhi (about 5 hour drive). We both had terrible trips back to the US as well - almost missed connecting flight, forced to pay for carry-on luggage (a small back pack!) and duty-free goods by the Air India staff last minute. Just terrible experience all around. Never again with AI! The ONLY good thing was the air hostesses were kind and patient - example: they made sure people with food allergies got their correct.

It would have been perfect if there was onboard entertainment.

Food was unfit even for prisoners. larger front seats are terribly uncomfortable, which is ironic. Thorough need to upgrade aircraft on such a long route.

Food could be better they need a better caterer in DC flight from India always has better food

Everything! To start with, seats, food tray table, entertainment console all are broken! Imposing duty free baggage fees for $250 as a surprise penalty cannot be appreciated! Airlines should be responsible for transferring the checked baggages to the connecting flight. Having customer go through the transfer is painful considering the travel tiredness! No soft drinks served on flight is another crumble!

Old creaky plane, poor entertainment, USB port did not work. Food was ok.

Old fittings. Went business class. Staff not very considerate regards comfort.

Very old plane. Broken tray tables n seats. Entertainment system super slow to operate and very little content.

Service was good, crew response was prompt. The baked fish and Malay fish as well as the sauces with them were bland.

Screen are not working. Windows not clean. Staff is very good. Food is okay. Experience is good. I hope the up coming is more then betters for others airlines thank you.
