I recently flew with Porter Airlines on Flight PD372 on October 30th, and unfortunately, had a very disappointing experience. At the gate, one of their attendants gave me two boarding passes. I assumed these were for my itinerary from Vancouver to Montreal and back, but one of the boarding passes unexpectedly included a connecting flight to Toronto, which was never part of my booking or invoice. As a result of this error, my checked baggage was mistakenly routed to Toronto. When I contacted Porter’s customer service, I spoke to an agent who apologized on behalf of the attendant (employee number 13209961) and promised to have my luggage flown back to Montreal. However, shortly after, I was told there was nothing they could do except for me to travel to Toronto myself to pick up my bag. This is highly unreasonable and unfair, considering the issue was caused by their staff printing the wrong boarding pass. This entire situation caused me significant inconvenience and stress. I expected Porter to correct the mistake and deliver my luggage as originally planned, but instead, I was left with the burden of fixing an error that was not mine. I even have a photo of the staff badge of the employee who made the promise, yet the company still failed to honor it. I hope Porter Airlines reviews their internal communication and baggage handling procedures to prevent this from happening to other passengers. Customer care and responsibility fell short in this experience, and I am still waiting for a satisfactory resolution.

FAQs about flying to San Francisco

Getting around San Francisco

Renting a car in San Francisco is more trouble than it’s worth. The city is covered with steep hills and one-way streets, traffic backups can be a nightmare and parking is scarce and expensive. You’ll only need a car if you’re heading out of town. It’s easy to get around on foot and the public transportation system can get you anywhere else. San Francisco’s main transportation network is the San Francisco Municipal Railway (Muni). It has 100 bus lines with electric trolley buses and the famous historic cable cars. Riding one of the cable cars from the Nob Hill down to Fisherman’s Wharf is an integral part of the San Francisco tourist experience. Check out the Muni Passports that offer unlimited rides for several days. Biking is a popular way to get around, but you’ll have to steel yourself to get up and over some of the hills. The easiest way to get a cab is calling ahead or lining up for one at a hotel stand. To get out of the city, you can hop aboard the Bay Area Rapid Transit (BART), the fast and efficient subway linking the city to the East Bay. You can also catch one of the many ferries sailing for Sausalito, Larkspur and Tiburon.   

What is good to know if travelling to San Francisco?

  • Golden Gate Park, larger than Central Park in New York, is a wonderful green space. It boasts some major attractions such as the Japanese Tea Garden, the Music Concourse Area, the M. H. de Young Memorial Museum and the Academy of Sciences, one of the largest natural history museums in the world. 
  • San Francisco Botanical Garden at Strybing Arboretum has more than 7,500 plant species. The National AIDS Memorial Grove was first envisioned in 1988 by a small group of San Franciscans who were looking for a way to express their grief at the deaths of so many family members and friends. Today, this serene space is a living tribute to all whose lives have been touched by AIDS.
  • A starter list of free attractions for those on a budget includes the Cable Car Museum; Creativity Explored; Musée Mécanique in Fisherman’s Wharf, home to one of the largest privately owned collection of coin-operated mechanical musical instruments and antique arcade machines in the world; Mission Dolores (although the suggested donation is $5), Precita Eyes Mural Arts and Visitors Centre; the Randall Museum (where children and adults can explore the creative aspects of art and science); galleries at the San Francisco Art Institute; the Wells Fargo Bank History Museum and the Tattoo Art Museum.
  • Alcatraz: more than just the prison where Al Capone and Robert Stroud and others languished, the island was the location of the first U.S. fort and lighthouse on the West Coast. Make reservations in advance, perhaps as you book your cheap flights to San Francisco, as tours fill up quickly. If visiting at the end of September, watch or join the Alcatraz Invitational Swim.
  • Wine country is just an hour or so from San Francisco. Most of California’s wineries are in Napa Valley and Sonoma Valley. Napa Valley has more wineries and attracts more tourists. Sonoma is lower key with family-run wineries.
  • Pick up a CityPass. For little more than $50 you get a book containing tickets to San Francisco’s greatest attractions, at savings of almost 50 per cent. It’s valid for nine days from the first day of use and contains admission tickets to the following attractions: Muni & Cable Car 7-Day Passport, California Academy of Sciences, Blue & Gold Fleet Bay Cruise Adventure, Aquarium of the Bay and SF Museum of Modern Art.
