Utilities for ExpertFlyer

Install from Chrome Web Store

Utilities for automating repetitive manual actions in ExpertFlyer, namely creating flight alerts for multiple dates at once.

Note: This extension is not affiliated with ExpertFlyer.

How to use: Bulk Alerts

1. Login to ExpertFlyer, then click Create New Flight Alert.

2. In the form at the bottom of the page, specify a flight route (including origin and destination airports in the format of e.g. NH7 SFO-NRT), a date range, the fare class code, and quantity. Click Queue Alerts.

(Note: As of version 0.10, this form can be accessed from the Flight Availability and Awards & Upgrades search result pages by clicking the 🤖 button)

3. Click Start, then don't touch or open other ExpertFlyer tabs until the runner is done.

Remember to be mindful of ExpertFlyer's limit of 200 active flight alerts. The extension will not stop you from trying to make more than 200 extensions, though it does rate limit the form submissions.

Other features

• A "Depaginate" button appears the bottom of paginated flight alert lists. This removes pagination and shows everything on one page.
• Flight alerts can be selected with a checkbox on the right side, then deleted or resubmitted in bulk.
  • Optionally, deleted alerts can be re-added back to the queue used by the bulk adding feature described above.
  • You can shift-click to select a range of consecutive rows
• Rows with "Yes" or non-zero availability are highlighted in green for easier visual identification on the Awards & Upgrades search page.
• Lists of flight alerts (in queue) can be imported or exported as JSON
• On the Flight Timetables page, you can easily save and restore filter settings in a single click (useful when switching between endpoints)
• On the Awards & Upgrades and Flight Availability search result pages, you can navigate to previous/next date ranges with a single click
• On the Flight Timetables page, you can view individual flights or the whole page worth of flights on GCMap
• On the Flight Timetables page, you can filter by some additional properties: origin/destination country/state, number of stops, flight frequency

Troubleshooting

This extension uses Chrome's Manifest Version 3 which requires the use of Service Workers. This support seems to be a bit buggy still and sometimes the Service Worker is suspended by the browser and not correctly re-awoken when incoming messages occur (maybe/hopefully fixed in Chrome 110?). If the runner appears to stop, try loading the Create New Flight Alert form page anew.

Development notes

For this simple browser extension I wanted to avoid the need for any compilation step and learn about a new frontend library, so this extension uses Lit and ES Modules.
