Plane ticket price went down by 40% two weeks after I booked it. Is there anything I can do to get a refund?

Unless you bought a high fare class that explicitly allows for cancellations at no penalty (unlikely given the price you paid), there's almost certainly nothing you can do. Sorry!

As for the future, buying airplane tickets is tough, but I have had moderate success doing the following -- especially for international travel where prices can fluctuate wildly:

• Start monitoring the price early (~3 months before the trip). Sign up for alerts with flights.google.com or similar, and actually write down the price each day for a couple weeks. You may notice that the prices tend to be lowest when booking on Tuesdays and Wednesdays, and highest on Thursdays and Fridays.
• After those two weeks have gone by, start looking for days when the price is lowest. Monitor the trends. Sometimes you get lucky, and the prices dips even lower than during your 2-week waiting period, but more often it is cyclic, and will simply occasionally return to the lowest price during that waiting period. Often on Tuesday afternoon.
• On one of those low price days, buy the ticket. (Ideally buy directly from the airline rather than expedia or similar).
• Don't wait any longer than ~6 weeks before departure to buy the ticket.

This is, of course, just a rule of thumb method, but it does tend to work decently. I was able to get a ticket ~$450 less than the "average" rate for a trip to the UK recently with this method.

In my experience there is a sweet spot for the lowest prices between 3 months and 6 weeks before departure, but sometimes waiting until the last couple weeks can really pay off (presumably when a plane isn't filling). It's up to you to decide how risk-averse you are!

Yes, you can almost certainly get some of the difference back - although the exact details will depend on the airline...

As mentioned in Taking advantage of Jetblue sale when I already bought ticket?, United airlines will give you a full refund of the difference minus $50 if you bought the ticket less than 30 days ago. Other airlines may have similar policies.

If you don't quality for a policy like that, then you could still get the difference back as a credit voucher, less whatever the change fee is (likely between $150 and $250). This is generally possible even if the airline doesn't have a specific policy on price drops - in effect you are just making a "change" to the flight which causes it to be re-priced at the current fares. After paying the change fee, the difference will be refunded as as credit on the airline.

You can also achieve the same thing by canceling the booking (which results in a credit, minus cancel fee), and then rebooking at the current prices using your credit. This works because despite your fare being "non-refundable", you can generally still make changes on the fare, or even cancel it and get a credit - you just can't get the resulting credit refunded back to you as "cash". Some airlines do have fares that don't allow changes in which case this may not work, but these fares are still fairly rare - especially for international flights.

Your best course of action is to contact Expedia and see what they offer. If that doesn't work, try contacting the airline directly.

Most (but not all) tickets are changeable. You pay the difference in ticket price plus a change fee. If the new ticket is cheaper than the old one, you do get a refund.

The reason why the ticket is cheaper was that Air Canada opened up a lower fare class that previously was blocked. You can try to change your existing ticket to the new fare class. Expect to pay about $200 in change fees, but you may be be able get around $500 back this way.

You should read the confirmation e-mail that spells out the fare rules for your ticket. Make sure you understand what the rules and fees for changes are and whether the cheaper ticket comes with some extra fees (seat reservation, bags, etc.). Then call the airline directly.

If possible, make sure you know the fare class of your current ticket and the new fare class. Ideally you open the conversation with something like "Hi, can I change my ticket from a G fare to an A fare". If you don't know how to do get the fare classes, try "Hi, I see that the price on your website for my ticket is a lot lower now, can I change my ticket to the lower fare?"

You may be get lucky with an agent since up- or down-faring is about the smallest change you can do to a flight and they may waive or discount the change fee. This would also depend if you have any status with the airline.

Depending on the arrangement between Expedia and Air Canada, Air Canada may refuse to execute a change. In this case, you can try the same approach with Expedia, but I would start with the airline.

My fare is not refundable: If you purchased a non refundable fare and wish to cancel your booking online, the value of your ticket will be banked for use as a future travel credit. To use the value of an unused ticket for future travel, please contact Air Canada Reservations. You may also want to refer to the Refund Services page for detailed information on how refunds are processed, and how you can apply your unused ticket value to the purchase of a new ticket.

Make sure you can quote this during the call with airline. If push comes to shove, you can cancel, and use the the travel credit to book to the new ticket. In this case you would not end up with cash but travel credit, but that's still better than nothing.

I called Expedia. They offered to give me a voucher of 1700 CAD - 150 CAD fee = 1550 CAD that I could use for myself on the same airline, before October 2020.

The current pricing was influenced by yourself buying your ticket.

That means it makes no sense from the math alone to allow you to change.

That could be mathematically overcome if you pay extra to make that change possible. Your new price would not be much lower in total.

It is even possible that your ticket is cheaper now only because you bought it:

Imagine there are two seats left.
You book a seat.
The airline knows that the flight is booked mainly by couples.
The risk not to sell the single seat is great, so the price is reduced.

If you had not booked your flight, a pair of seats for a couple would be still available, and no reason for lowering the price would exist.

You caused the low price yourself by buying a ticket earlier.

The example shows that it does not make sense on the level of math alone, so you should not expect to get the cheaper ticket for a lower price¹. The lower price is an offer to people who do not yet have a ticket, not for you.²

(This does not strictly mean that you can not get the reduced ticket, because companies do not always behave rational.)

¹ _{The example is contrived and only applies to the last two seats on the plane. As a general rule, the opposite is true: Last-minute prices are the lower, the fewer tickets have been sold. Buying early drives late prices up.}

²_{(It would be ethically controversial, but there may be a way to cheat that system.)}

In an immediate sense it’s not likely you can demand relief, but there are specific uncommon circumstances when the fare includes fees, refunds, or rates imposed by a sovereign power, so a large fare change on an international flight from Vancouver to Buenos Aires might be the result of an action that would include you.

You can nonetheless request assistance from the ticket vendor and if they give you no relief then the airline. Both of those classes of vendors are rumored to be more responsive to pleas on social media than elsewhere.

Ticket brokers buy blocks of seats at a discount from face value and assume the pricing risks and no-sake costs. An unsold ticket is a total loss, so if they don’t sell their inventory of tickets early they’re forced into a discounting spiral to the bottom - last minute $100 round trip fares and the like.

Airlines like early ticket sales to make more precise rate setting and operational planning decisions and they are keenly aware that an aggrieved traveler burned by a large fare change will retell that story for years and persuade hundreds of other travelers to delay their own ticket purchases. If you do a lot of traveling or plan to do a lot of traveling buying tickets from the same vendor or flying on the same carrier this has an effect on the latitude their agents have for granting relief.

There’s no benefit to being outraged to the vendor’s or airline’s customer service people on any medium, they’re given a guidebook of policies and procedures and only limited personal latitude for interpreting them. You are more likely to be satisfied by the outcome if you are someone they want to help than if you are someone they want to have go away.

That said, if you can’t obtain any relief, then as long as you stick to factual truth and the effect on your own person, you’re free to make your story progressively more widely known until they see the cost of making you a satisfied customer as less than the consequential cost of lost reputation. Don’t impute motives, cast invectives, or make generally disparaging comments - that could boomerang on you. Stick to the facts of the story and how it actually makes you feel and don’t use the actual names of any company’s employees so that you neither libel nor defame any party and avoid legal entanglements.

If you purchased your tickets with a credit card, many cards have a price protection policy for this kind of scenario. Credit card companies usually use the example of a TV going on sale a few days after purchase, but it's worth checking if your card also covers flight price changes.

You didn't "lose" the money, you paid them to be sure you have a seat. That low price will not last for long, so a customer who can only pay 1000 could easily miss the opportunity and get no ticket at all.

If you can tolerate not to get a ticket at all, you can make a bid on a flight (plenty of sites do this, e.g. skyauction). If the ticket price ever drops below your bid, you will get a ticket. Otherwise you get nothing (but you get to keep your money of course).

I'm not sure if anything can be done right now to get your money back, other than to cancel and rebook with a lower price after paying the change of $ 200 CAD.

However for future travel, I'll point you to Flight Network's price drop Protection ( it's a Canadian online travel co. based out of Missisauga and I have never used them)
