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. Common transit points include Toronto Pearson International Airport (YYZ) and Philadelphia International Airport (PHL). 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.

For instance, Air Canada has initiatives aimed at reducing its carbon footprint, including investing in more fuel-efficient aircraft and offering carbon-offset programs. Choosing direct flights where available or routes with the fewest layovers can also reduce carbon emissions.

Additionally, selecting accommodations and activities that are environmentally conscious can further contribute to a sustainable travel experience.

Seats very comfortable; service efficient and pleasant; flight was on-time; boarding organized.

Starlink is great Crew was polite Business class didn’t get a welcome drink just water and snacks were ok

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

Good but airlines getting smaller. I didn't like the meal but the service was fine. Flight was fine and luggage arrived. So good.

They were fast and I like how they used to entertainment system to play video about the safety.

Hopped on time for the flight only to get deplaned and delayed another 2.5 hours.

Given I (and I’m assuming most people) have both carry in and a personal item included in their fare, I find it very unfair that on neither of my flights I was able to use the overhead for my small backpack because they were completely rammed with luggage, people personal items, jackets, hats and other items. So the only item I brought in had to be stuffed under my seat while they had their leg room and sat comfortable with all of their items in the overhead. This has to stop because I was uncomfortable on both flights when I only had one smaller item that could not be checked due to its contents (medication etc). Plenty of people could have checked theirs but chose not to and then took up the space allotment for 2 people.

Flight attendants had a little attitude. Food tastes no good.

From pre boarding to flight attendant, crew and baggage handler, excellent. Didn’t lost my luggage like West jet.
