app search not showing expected results

HI i Can Help you

Try resetting the App Store:

Close the App Store completely from the app switcher window by double clicking the Home button and swiping up the App Store preview pane until it disappears from the screen. You may have to look for the App Store pane by scrawling to the left.

Then sign out of the iTunes Store (in Settings).

Then do a forced restart. Hold down the Home and Wake/Sleep buttons at the same time for about 15-20 seconds until the Apple logo appears.

Then sign back into the iTunes Store.

BTW, it could be "that bad". I just checked on my iPad Air and while I can find Costco, neither Southwest Airlines nor Alaska Air shows up. This means that they have not developed apps approved by Apple. I use the United Airlines app all the time and many others are there, but apparently not those two.

You could try providing feedback to Apple here. http://www.apple.com/feedback/iphone.html

And yes, some apps do fall out of support although I would not expect those to do so.

I am in the U.S., so what I'm about to say may only apply to the U.S. Apple Store.

I just searched for "Southwest Airlines" in the App Store.

Here's what I found:

So the Southwest Airlines app shows as an iPhone app, but not an iPad app.

Within the body of the Southwest Airlines app writeup, it describes that the app is "compatible with iPad." But it's clearly designed for an iPhone. Get it from there if you can.

Excellent. Glad that worked out for you.

Enjoy your Apple gear.
