- Task 16: Search & Filter tests (37 tests) - departure/arrival cities, passenger count, cabin class
- Task 17: Arrival/Departure Tabs tests (45 tests) - tab switching, flight display, sorting
- Task 18: Flight List View tests (50 tests) - display, sorting, filtering, pagination, loading states
- Task 19: Flight Details Modal tests (40 tests) - opening/closing, content display, actions
- Task 20: Time & Date Filter tests (43 tests) - date selection, time ranges, calendar navigation

Tasks 21-25: Flight Details Tests (Flight Info, Passengers, Seats, Services, Fares)
- Task 21: Flight Info Display tests (40 tests) - basic info, airports, route visualization, timeline
- Task 22: Passenger Info tests (50 tests) - passenger list, details, services, special requirements

+# onetime
+
+> Ensure a function is only called once
+
+When called multiple times it will return the return value from the first call.
+
+*Unlike the module [once](https://github.com/isaacs/once), this one isn't naughty and extending `Function.prototype`.*
+
+## Install
+
+```sh
+npm install onetime
+```
+
+## Usage
+
+```js
+import onetime from 'onetime';
+
+let index = 0;
+
+const foo = onetime(() => ++index);
+
+foo(); //=> 1
+foo(); //=> 1
+foo(); //=> 1
+
+onetime.callCount(foo); //=> 3
+```
+
+```js
+import onetime from 'onetime';
+
+const foo = onetime(() => {}, {throw: true});
+
+foo();
+
+foo();
+//=> Error: Function `foo` can only be called once
+```
+
+## API
