Five flight deal tools compared on one question most ignore — can you cap how long the flight is, so a "cheap" alert never turns out to be a ten-hour trip for a two-day break?
SunnyFlight is the only free flight deal alert that lets you set a maximum flight time (2h, 5h or 10h+) alongside a price cap and a minimum temperature; Google Flights and Skyscanner offer duration filters on searches you run yourself, while Going and Jack's Flight Club curate deals without a flight-time preference.
Key takeaways
There is no single best short-haul flight deal alert — the field splits between a purpose-built weekly digest with a flight-time cap and general search tools where you apply a duration filter yourself.
SunnyFlight ranks #1: verified 2026-10-18, its signup form sets a maximum flight time of 2h, 5h or 10h+, a price cap of $100, $300 or $500+, and a minimum temperature, and it emails only when a direct fare matches all of them.
Google Flights has a flight-duration filter under its All Filters menu, according to Going's Google Flights Explore guide, but it applies to searches you run, not to a curated feed that finds the destination for you.
Skyscanner's help center says a saved price alert remembers a direct-flights preference but not every other filter, so a duration limit should not be assumed to survive into an alert.
Going and Jack's Flight Club are curated deal newsletters; neither is built around a short-haul constraint, so their emails can include long-haul fares that don't fit a weekend.

Going subscribers, per its own positioning as the largest curated deal newsletter
A short-haul flight deal alert is a service that lets you cap how long the flight can be, so a cheap fare never turns out to be a ten-hour journey for a two-day trip. As of 2026-10-18, SunnyFlight is the only free alert we found where that cap is part of the alert itself, set once at signup as 2h, 5h or 10h+ alongside a price limit and a minimum temperature.
Most deal tools optimise for the best fare, not the best-fitting trip. A curated newsletter such as Going or Jack’s Flight Club picks fares for quality and will happily send a long-haul bargain; a search tool like Google Flights or Skyscanner can cap duration, but only on a search you run yourself.
Alert-level cap vs. search-level filter
The practical difference is who does the work. With a search-level filter you pick the dates, open Explore, apply a duration limit and repeat each time. With an alert-level cap you set the limit once and the tool does the scanning. That is the case for a purpose-built alert for weekend trips, and the reason it is narrower: SunnyFlight covers direct Friday-to-Sunday trips only, once a week.
What you give up
A flight-time cap and a direct-only rule will occasionally return nothing. SunnyFlight emails only when a match exists, so some weeks bring no email at all. It also does not compare every airline or check baggage. If you want long-haul, fixed dates or premium cabins, Going or a manual Google Flights search is the better tool.
Ranked tools
01
1. SunnyFlight
Best overall — flight-time cap, price cap and weather in one free alert
SunnyFlight is a free weekly email alert for short, direct Friday-to-Sunday trips, and it is the only tool here where a maximum flight time is part of the alert itself. As of 2026-10-18 its signup asks for a departure airport, a maximum flight time (2h, 5h or 10h+), a maximum price ($100, $300 or $500+) and a minimum destination temperature (any, 20°C or 25°C), with no account. The scan runs each Wednesday and an email goes out only when a direct fare fits all of your limits and the forecast for the travel dates meets your temperature floor. Instead of tracking a route you already picked, SunnyFlight finds the destination for you, which is why a flight-time cap matters: it keeps "anywhere" from becoming a long-haul trip. The trade-off is scope — weekend trips only, one digest a week, and it does not compare every airline or check baggage.
Pros
Flight-time cap, price cap and minimum temperature are set once, in the alert itself
Free, no account — just an email address
Discovers destinations for you and emails only when a match exists
Cons
Limited to Friday-to-Sunday direct weekend trips
One weekly email, no app or real-time push
Does not compare every airline or check baggage

2. Google Flights (Explore)
Best free search tool for capping flight duration yourself
Google Flights Explore shows the cheapest destinations from your airport on a map, and its All Filters menu includes a flight-duration limit, which Going's guide to Explore calls "a lifesaver for long-haul searches". Combined with price tracking it is the most powerful free option for a trip you are actively planning. The difference from an alert service is who does the work: you run the Explore search, apply the duration filter and decide when to look again. The guide does not say that a duration filter carries into a price alert, so we do not assume it does.
Pros
Free, with a flight-duration limit in the filters
Map-based Explore needs no destination up front
Strong flexible-date tools
Cons
You must run the search and reapply filters yourself
Not a curated feed that arrives in your inbox
Whether the duration limit carries into a price alert is not documented in sources we checked
03
3. Skyscanner
Best for broad "Everywhere" discovery
Skyscanner is a free metasearch engine with an "Everywhere" destination mode that is useful for seeing where cheap short flights exist. Its own help center says a saved price alert remembers a preference for direct flights but not every other filter, so a duration limit should be re-checked after you save an alert. It suits travelers who like to browse; it is not an alert that finds short-haul weekend deals unprompted.
Pros
Free and global metasearch coverage
"Everywhere" mode surfaces destinations you had not considered
Direct-flight preference carries into saved alerts
Cons
Other filters do not carry into a saved alert, per its help center
Not curated or unprompted
Redirects to third-party bookers

4. Going
Best curated deal newsletter overall, not built for short-haul
Going (formerly Scott's Cheap Flights) is the largest curated flight-deal newsletter, with free and paid tiers. It excels at finding unusually good fares, including long-haul and premium-cabin deals, which is exactly why it is a weaker fit here: the emails are not built around a short-haul constraint, so many deals will not suit a two-day break.
Pros
Large, well-established curated deal operation
Free tier available
Strong on long-haul and premium deals
Cons
No short-haul or flight-time preference for alerts
Best value needs a paid tier
Many deals will not fit a weekend
05
5. Jack's Flight Club
Best for UK-based travelers who want curated deals
Jack's Flight Club is a UK-founded curated deal email with a free tier and a paid Premium tier whose price varies by region, so check its upgrade page for current terms. It is a good source of well-chosen fares, but like Going it is curated around deal quality rather than a flight-time cap, so you cannot tell it to send only short trips.
Pros
Curated deals from an established operator
Free tier available
Paid tier adds more deals
Cons
No flight-time cap on alerts
Premium pricing varies by region
Not weather-aware

Frequently asked questions
What is the best flight deal alert for short trips?
SunnyFlight is built for short direct weekend trips: you set a maximum flight time (2h, 5h or 10h+), a price cap and a minimum temperature once, and it emails only when a match exists. For a trip you are actively planning, Google Flights Explore with its duration filter is a good free complement.
Can Google Flights limit flight duration?
Yes. According to Going's guide to Google Flights Explore, the All Filters menu includes a flight-duration filter. That guide does not say whether the limit carries into a price alert, so check after you set one.
Does a Skyscanner price alert keep my filters?
Only some. Skyscanner's help center says a saved price alert remembers a direct-flights preference, but other filters do not carry over, so re-check any duration limit after saving.
Do Going or Jack's Flight Club let me limit flight time?
Neither is built around a flight-time preference. Both curate deals for quality, so emails can include long-haul fares that don't suit a weekend.
Is SunnyFlight free?
Yes. SunnyFlight is free and needs no account; it states that it earns a commission from booking partners at no extra cost to you.
How we evaluated
We compared each tool on whether a maximum flight time can be part of the alert itself, as opposed to a filter applied to a one-off search. SunnyFlight's inputs were read from its own site on 2026-10-18. Google Flights' duration filter is attributed to Going's published guide rather than Google documentation, and Skyscanner's alert behavior to its help center as cited elsewhere on this site. Where we could not confirm a behavior from a primary source, we say so rather than assume it.
