Airport Lounge Access Checker by Card

WHAT IT DOES

This script scans credit card review and comparison pages for airport lounge access benefits—Priority Pass, Centurion, Delta Sky Club, United Club, and others—and displays a floating overlay showing lounge access status based on your stored card profile. It extracts lounge access program names and conditions from the page, compares them against your user-defined lounge access profile (stored per domain), and displays a compatibility status with color-coded indicators: green for included, red for not included. A summary of total lounge visits per card and a breakdown by program are provided. A one-click export function saves lounge access data as CSV or JSON. All lounge access profiles and snapshots are stored per domain locally.

WHERE IT RUNS

Works on any credit card review or comparison page—The Points Guy, NerdWallet, CreditCards.com, or any page displaying credit card lounge access benefits. The script detects card containers and lounge program mentions using common patterns and selectors, making it compatible with most credit card review sites.

HOW TO USE

The panel appears automatically when you visit a card review page. First, set up your lounge profile by selecting which lounge programs you have access to (Priority Pass, Centurion, Delta Sky Club, United Club, etc.)—click "Save Profile" to store it for the current domain. The panel then detects cards with lounge access benefits and displays a comparison matrix with lounge programs as rows and cards as columns. Your selected lounge programs are marked with a star (⭐). Cards that include a lounge program show a green checkmark (✅), while cards that don't show a red cross (❌). Cards that include programs in your profile are highlighted with a green background. The "Matches your profile" section shows which lounge programs you've selected that appear on any detected card. Click "Refresh Data" to rescan for updated card information. Export lounge access data as CSV or JSON. Use "Clear History" to reset stored snapshots for the current domain. The panel automatically saves a snapshot each time you check lounge access.

TECHNICAL MECHANISM: LOUNGE ACCESS EXTRACTION WITH PROFILE-BASED MATCHING AND COLOR-CODING

The script uses a comprehensive detection strategy. It searches for card containers using selectors (.card, .credit-card, .card-offer, .card-comparison) and falls back to scanning divs with lounge-related keywords (lounge, priority pass, centurion, sky club, united club, admirals club). For each card, it extracts the name from card-name elements and checks for lounge program mentions using a predefined list of lounge programs. The script uses context analysis to determine if a lounge program is included—checking for indicators like ✓, ✔, "included," "free," or "access." The lounge access profile is stored per domain using GM_setValue with a list of selected lounge programs. The compatibility check marks cards with green checkmarks for programs that are included and red crosses for those not included. Programs matching the user's profile are starred and highlighted with a green background for included matches. Each snapshot stores the card list with lounge data, capped at 30 entries per domain. The export function generates CSV with cards as columns and lounge programs as rows.

THE PANEL

The lounge access checker appears in a draggable, resizable panel that remembers its position per site. The panel shows the comparison matrix with color-coded indicators, profile matches summary, and profile editor. Drag by the header to reposition, collapse to a compact icon with a click, and resize using the bottom-right corner. The panel snaps to screen edges for tidy placement and closes with the Escape key. All settings—panel position—persist per website using GM_setValue, so your view returns exactly as you left it.

PLEASE NOTE

This script requires the free BotGentz extension to run. The script relies on common card review page structures—if a site uses a non-standard layout, lounge detection may be incomplete. The script does not access your financial account credentials—all data is read from the visible page and stored locally. The lounge program detection uses a predefined list of common lounge programs; new or less common programs may not be detected. The profile is stored per domain; you can set different profiles for different use cases. All data is stored locally in your browser via GM_setValue and never transmitted.
