Sharing three flight booking tips that I don't see mentioned so often

Hi! I feel flight booking tips often revolve around flexibility. Flying on Tuesdays or on Christmas Eve might be cheaper, but it’s quite inconvenient.

Instead, I am sharing three strategies I use to make high-demand / expensive flights a little more affordable. It won’t get you the absolute cheapest fare, but can help bring a $1300 super convenient direct flight to, e.g. $800.

1. Spare multicity
You all know about hidden-city flights. It’s a bit the same idea but without the inconvenience. Instead of exiting at the layover, you only fly a portion of an open-jaw itinerary.

One way ($500)
LAX → ORD (May 4) | Flown

Open-jaw ($300)
LAX → ORD (May 4) | Flown
ORD → JFK (May 16) | Dropped

Note that here ORD is not a connection, but a destination with departure on another journey. So you can check a bag and don’t have to worry about your flight being rerouted in case of delay / cancellation. Also, the risk of being penalised by the airline is pretty low. You’re not dropping a segment, simply having a no-show on another journey you won’t even check in for. In that sense, it’s very similar to a Throwaway Return ticket, but running the search with a different destination can sometimes yield better savings.

2. Long layover
It’s a pretty common way for flexible travelers to save on flights: turn a terribly long layover into an extra city stop and enjoy it instead. But you can also use it on a predefined itinerary. Say you have a 2-day stop in a city as part of a trip with several destinations; your first instinct might be to look for multicity tickets or separate tickets. Instead, use ITA Matrix to filter for a long stop where you need to be; it might turn up cheaper. If the flight is not available online, try calling the airline to book it.

3. Nested trips
You might know about back-to-back ticketing. When instead of booking two similar roundtrips sequentially, you nest them into each other:

Sequential

Tickets Trip 1.1 Trip 1.2 Trip 2.1 Trip 2.2
$500 A → B B → A
$500 A → B B → A

Back-to-back

Tickets Trip 1.1 Trip 1.2 Trip 2.1 Trip 2.2
$250 A → B A → B
$300 B → A A → B

Using open-jaw tickets, you can also achieve that with two trips that have different destinations, e.g.:

Tickets Trip 1.1 Trip 1.2 Trip 2.1 Trip 2.2
Open-jaw #1 Paris → LA Denver → Paris
Open-jaw #2 LA → Paris Paris → Denver

It’s not guaranteed to be cheaper, but it can help you reach minimum stay requirements that open access to lower fare classes.

These aren’t magical solutions, but running these extra checks every time I book flights got me a good amount of savings over time!

EDIT: Number #3 confused a bit people, so adding two elements:
- from u/SCDWS (thank you!): “It’s like booking a return trip and skipping the return flight, except instead of a return trip, it’s a multi-city trip with a different final destination”
- you can call the airline to cancel the flight you don’t need instead of a no-show (e.g. say you have a medical issue) - you might be able to get a refund for part of the cost (e.g. the airport fees).

Unless you can show some concrete examples, I don’t believe any of these will offer any particular savings, and you’re increasing your search effort sixfold.

There’s a small group of people who have a hobby of doing stuff like this. It’s called fuel dumping and it’s getting harder to do.

Old blog example.

@Marin
OP’s tricks aren’t really fuel dumping and are a lot easier to use.

The first tip is kind of FD. I found an example that worked just now and brought my ticket from $500 to $330 when booking multi-city A-B then B-C. Interestingly, booking it on one ticket A-B-C prices at $380. Didn’t look at the fare details to see if it’s YQ though.

@Marin
The first tip isn’t fuel dumping. It’s well known that domestic one-way fares can be more expensive than a round trip. It’s just the fare. YQ not really a thing for domestic US flights.

Based on the linked article, FD seems like a methodology that can help find spare multicity flights. However, my preferred approach is to search for extra flights that can serve another trip - sometimes the price is not so much lower, but I get a flight that I might use and that I kinda got “for free”.

@Marin
Don’t know much about FD, but it might explain some of the price differences. Minimum stay requirements are probably an important factor - same reason why roundtrips are often cheaper than one-way on international routes.

Sure you are increasing your search effort, and not everyone will want to spend the extra time, but it does work sometimes. Here are some examples I just ran on Google Flights, you can check them yourself (assuming prices don’t change).

  1. Spare multicity
    LX41 (Jan 12) | $2143
    LX41 (Jan 12) + LX328 (Jan 16) | $1129

  2. Long layover
    Flights: BA955 (Feb 12) + BA227 (Feb 13)
    Long Layover: $766
    Multicity: $786
    Separate tickets: $2,529

  3. Nested trips
    Flights: UA26, UA564 (Jan 13) - UA493, UA27 (Jan 17) + UA147 (Jan 20) - UA110 (Jan 24)
    Sequential: $1545 + $1715 = $3262
    Nested: $993 + $1416 = $2409

Agree.

Using OP’s example in one of the comments below of the long layover:

Flights: BA955 (Feb 12) + BA227 (Feb 13)
Long Layover: $766
Multicity: $786
Separate tickets: $2,529

In this scenario, if OP wants to indeed fly from MUC to ATL, then why would one even bother to look at separate tickets? Especially MUC to LHR on Feb 12^(th) and LHR to ATL on Feb 13^(th), simply the following day? This is where OP’s example falls short. A one-way from MUC to ATL is $784 on British Airways (with a stop in LHR). And it’s a same-day ticket. No need to stay overnight at LHR and depart from LHR to ATL the following day.

In this scenario, OP uses separate tickets (same flight numbers as above) as an example for the “hack”. MUC to LHR on Feb 12 is $83 and LHR to ATL is $2,836 (based on my search right this minute). But again, this is where OP’s example falls short. It would make absolutely no sense to book this as separate tickets. Plus, if they are booked on separate tickets, if there are any issues with the flight from MUC to LHR on Feb 12^(th), say it’s canceled and rescheduled for the next day, then OP would not make the flight from LHR to ATL and that would be classified as a no-show. Or OP would have to reschedule the LHR to ATL flight at a premium cost (much greater than the original flight cost for a last-minute booking).

OP’s other examples below are in Jan, I presume Jan 2025 so booking a flight just one to two weeks from now will be much much more expensive than booking 4-6 months before.

@Ashton
Thanks for doing all the checks. Your points are valid, and the examples I picked are probably not representative of what I would actually book if I had to fly these routes - searched for examples that show the price differences. But it doesn’t mean the strategies are not helpful. There is no magic trick to make all flights cheaper, it’s about trying various ways, over multiple trips, and saving some of the times. Any single strategy has a low likelihood of yielding a deal, but running many of these checks every time you book a flight is likely to help you save over time.

Also, these strategies mostly work for high-demand / expensive flights (hence the January example). You’ll always have a better deal booking early on, off-peak, or on less convenient routes. But some travelers aren’t that flexible; sometimes there is this one flight that you really want but that got too expensive - and it helps in these cases.

Huh, these are all pretty clever and new tips for me that I haven’t seen before, thanks for sharing!

Curious how often you’re seeing multicity flights being cheaper than one-ways though.

Edit: apparently you can even call in to cancel your second flight and get more money back in the form of credits from the airline :scream_cat: this is game-changing.

@Sky
Yep haha, you can get part of the ticket price back sometimes (airport fees I think).

@Sky
Thanks! It depends a bit on your flying habits. You’re going to see these deals on the same type of flights that get cheaper with a roundtrip, often international flights with legacy carriers.

This confused the hell out of me.

@Tate
I’m glad I’m not the only one. OP what is an ITA matrix and can you do a “Nesting for Dummies” explanation? Maybe it’s too early in the morning for me.

I’m not OP, but ITA matrix is an advanced search tool that helps to find suitable flights with a good amount of parameters that you can define to your own taste. Basically, it’s like Google Flights on steroids. In fact, Google Flights uses ITA matrix in the back. However, it is not a booking site where you can purchase your tickets.

Regarding “Nesting”, I will leave that one for OP to clarify, since I’m also confused…

@True
Thank you so much!!

@True
If I make a weird itinerary using ITA matrix, how do I purchase it?

I just stick with one airline, accrue lots of points, and get discounts and special deals.
