A WordPress plugin to display the lowest travel prices for given routes/dates in your blog. Powers the flight price monitor here: https://escapefromberl.in

Download the plugin, copy the folder flightprices-monitor into the plugins directory; activate. Open Settings -> Flymon, add your Kiwi.com API key + affiliate id for deeplinks.

To display the price in your post or page, insert the shortcode trip_price in the paragraph.

Shortcode parameters & examples (+ default values):

• from: BER, berlin_de (required)
• to: MUC, innsbruck_at (required)
• earliest: 2023-01-30, tomorrow (now)
• latest: 2023-12-31, +2 weeks (+3 months from now)
• min_days (none)
• max_days (none)
• max_stops (0)
• transport: aircraft, bus, train -- comma-separated (aircraft)
• currency (EUR)
• locale (en)
• deeplink_type: search|booking (search)

For locations, use IATA codes or check out Kiwi's locations API.
For dates, you can use a wide range of expressions -- whatever can be parsed by PHP's strtotime().
For return trip search, both max and min days at destination must be specified. If none are set, we search for one way.

Examples:

[trip_price from="BER" to="MUC" earliest="tomorrow" latest="+6 months" currency="EUR"]
[trip_price from="LON" to="IST" earliest="+1 week" latest="+1 month" min_days="6" max_days="8" currency="GBP"]
[trip_price from="AMS" to="PAR" latest="+3 months" min_days="2" max_days="3" transport="train,bus"]
[trip_price from="NYC" to="TYO" transport="bus"]
