Yes, you will be able to use your United Gateway Card instantly after approval, if you log in to your MileagePlus online account and apply through the United Airlines website. If you get instantly approved, you will be able to use your United Gateway Card straight away, to make online purchases through the United Airlines website.
If this isn't your case, you will have to wait until you receive your United Gateway Card in the mail. This usually takes 7-10 business days from the time you get approved. If it's been longer than that but you still haven't received you United Gateway Card, you should call customer service at (800) 432-3117 to check on it.
