I used an obscure credit card perk to pay for $127 worth of travel expenses when American Airlines canceled 2 of my flights — see how

Flight delays and cancellations can be costly. Hours and even days can be wasted that could lead to unplanned expenses through no fault of a traveler's.

I was left high and dry by American Airlines in June when flying home from Bogota, Colombia in June. Two back-to-back flight cancellations extended my trip and left me with no clear way to get home.

At first, I was faced with an eight-hour delay that quickly turned into an overnight stay. American was going to pay for a hotel but I'd be largely on my own for meals, plus any other expenses I might incur thanks to the extended trip.

In total, I incurred $127.39 extra expenses incurred from the delay but because of the credit card I used to book the trip, I was reimbursed for all of it. Here's how my credit card ended up saving my bank account.

The Chase Sapphire Reserve is a premium travel credit card that costs $550 per year but comes with perks like a free $300 in travel credits, complimentary Lyft Pink membership for a year, and built-in travel insurance.

While many credit cards offer some form of travel insurance, not all are equal and some only kick in if the cardholder dies in a plane crash. But the Sapphire Reserve offers three types: trip cancellation/interruption insurance, baggage delay insurance, and travel delay reimbursement.

As its name suggests, trip cancellation/interruption insurance covers expenses when a trip is "cut short or canceled" due to instances like sickness, severe weather, injury, loss of life, terrorist action, hijacking, and unpostponable jury duty or court subpoena. Chase will cover up to $10,000 per trip, if eligible.

Baggage delay insurance covers "essential purchases" in the event luggage is lost by an airline, bus company, cruise ship operator, or train company for more than six hours.

And finally, trip delay insurance covers travelers if a trip is delayed for more than six hours or requires an overnight stay. This is the insurance for which I qualified when American canceled my flight and rescheduled me for a later flight to New York.

This insurance is pretty comprehensive and will cover meals, lodging, transportation, and additional unreimbursed expenses up to $500. Coverage only applies if the flight was booked using the Sapphire Reserve and I make sure I book every trip using the card for that reason.

The perk will also apply to mileage award tickets, even if only the taxes are paid using the card. If travelers are booking flights with a travel credit, they can also get the coverage by paying as little as $.01 using the card.

I called up Chase while stranded in Colombia to confirm I could use the credit and they gave me the green light. I didn't need to call Chase but this was my first time using the perk so I wanted to be sure I was using it correctly.

I was ecstatic to have $500 at my disposal because that goes really far in Colombia. But I wasn't trying to extend my vacation, I wanted out.

My first plan was to take the 12:15 a.m. flight to New York and so I began my long wait in the airport. I took a walk and started plotting how I could spend $500.

American, for its part, gave all the passengers on my first canceled flight a meal voucher for around $12. I decided to use that for my first meal and save Chase's travel insurer some money.

But beyond that, I was hesitant to spend any money because I didn't want to get into a situation where something wasn't covered. Again, this was my first time using the perk.

So, I left Colombia using exactly $0 of the $500 and didn't spend anything until landing back in the US. After my second flight to New York was canceled, I was routed to Phoenix via Dallas leaving the same night because I was starting a trip to Phoenix and American couldn't get me home in time for my flight to get there.

After I landed in Dallas, American had given me a hotel voucher, at my request, so I could have a shower during my four-hour layover. I took a hotel shuttle to the hotel, around five miles from the airport itself, and only planned to shower in the room, then head back to the airport.

The shuttle, however, was hourly, and I only had 20 minutes from the time I got to the hotel to the time it was leaving again. That didn't include checking in and getting to the room.

So, I figured, what better time to use the $500. I took my time in the shower and then ordered a Lyft for $19.27, including tip, to get me back to the airport.

Transportation, after all, is covered under the rules of the perk. Of course, I wouldn't know for sure until I submitted the claim.

I got to the airport and American, once more, had given me another $12 meal voucher. But it was too early to eat so I only used around $6 of it to buy two water bottles for the flight to Phoenix.

I landed in Phoenix after a nightmare of a travel experience and asked American if they'd arrange a taxi for me to get to my family's home. I thought it was a reasonable request being as I arrived a day early and my family members couldn't pick me up.

But the airline didn't think so and I was on my own to arrange an Uber, at peak time, for a total of $107.65 with a tip. Time to file my claim.

First, I needed proof of the delay being greater than six hours. That was easy as American sent an email telling me that I was rebooked on a later flight after the first flight cancellation.

Next, I needed my expenses. All of my Uber and Lyft receipts were digital, so getting them was just a matter of taking screenshots from their mobile applications.

Then, I needed a verification letter from American confirming that my flight was delayed due to a covered reason. In my case, a mechanical delay.

Even that was surprisingly easy. American has a request form just for "delay verification requests."

That letter came three days later and I was then able to submit the claim.

To my surprise, it was approved with no questions asked three days later.

The check did take a while to arrive but I took it straight to the bank.

And with that, my escape from Colombia was complete. I even got credit card points from the two purchases.
