FAQs - booking Maryland flights

  • What are some common layovers on the route from Ottawa to Maryland?

    Direct flights from Ottawa to Maryland are uncommon, so, typically, you will have a layover.

The specific layover location depends largely on the airline and the available routes. Carriers like Air Canada and United Airlines often offer these connecting flights.

Crew were welcoming, accommodating and they worked hard to find places for all carry on.

very average service no complimentary alcoholics drinks unlike other airlines such as Porter airlines No decent seats available during check-in time the day before

It was great. There were some issues prior to takeoff. The weather was poor so we had to go through deicing, and we were delayed a bit by the pilots' concern about one of the engines, but that's aviation. The pilots handled everything with aplomb, and kept us apprised

I dread trans-Pacific flights. They are very long. This was my first time on Universal, and it was my best crossing ever. The staff were professional, the hospitality was great, and the food was delicious. The entertainment system filled the long flight hours. I will seek out Universal flights from now onwards. 🙂

My flight was delayed about 1 1/2 hours in Chicago, but other then that it was a good flight.

The flight was delayed, it took longer than anticipated because of weather, and they broke my luggage.

lots of delays the crew were unclear about where to pick up my carry-on, which they took from me to check in on the plane.

My connecting gate in .Chicago was across the aisle from my arriving gate. Otherwise I would not have made my connection. So that was very fortunate.

My flight was delayed by a whole day, so I lost a day of my vacation.

How would you rate my experience when I was stuck in YOW without being offered a cup of water by the airline?
