I've had a Chase Sapphire Reserve® card in my wallet for about eight years, and it'll stay there so long as the perks remain as good as they are now.

The card carries a steep annual fee of $550, but it's still one of the best travel cards on the market. I could downgrade to the Chase Sapphire Preferred® Card, which costs only $95 per year. However, I easily earn back my annual fee -- and then some -- through rewards.

Here are three of the biggest reasons I expect to keep this card for years to come.

1. I fly for free several times a year

The Chase Sapphire Reserve® card pays a credit for your first $300 in travel spending each year. So if you travel even just once per year, you're practically guaranteed to get $300 back.

Earning categories include:

• 10x total points on hotels and car rentals through Chase Travel℠ immediately after the first $300 is spent on travel purchases annually
• 5x total points on air travel through Chase Travel℠ immediately after the first $300 is spent on travel purchases annually
• 3x points on other travel and dining
• 1x points on all other purchases

On top of that, your points are worth 50% more when you redeem them for travel through Chase.

Between the annual credit, the rewards points, and the bonus redemption rate, I've saved over $1,000 on airfare in the past year alone.

2. I use DoorDash and Lyft

Chase Sapphire Reserve® cardholders get a free DoorDash DashPass subscription (normally $10 per month) and a $5 monthly DoorDash credit. DashPass gets you $0 delivery fees and reduced service fees. I save $5 to $10 on every order, and I order from DoorDash once or twice a week. That means I'm saving a few hundred bucks a year.

I also use rideshare services to get around sometimes, and my card got me a free Lyft Pink subscription. Granted, this was a limited-time promotion that has since ended; my free Pink membership runs out in November. But until then, I'll enjoy faster pickup times and 5% off every ride, which for me is worth at least $40 a year.

And if history is any guide, there will be more valuable limited-time promotions to come.

3. I use my Priority Pass Select™ membership every chance I get

Chase Sapphire Reserve® cardholders get access to over 1,300 Priority Pass airport lounges.

There's no limit to how many lounge visits they can make, and they can bring a guest for free. That means my partner and I almost always have a place to relax with free food and drinks before our flights.

This is a rare and valuable perk that most cards -- including the Chase Sapphire Preferred® Card -- don't offer. Without the Chase Sapphire Reserve® card, a similar Priority Pass membership costs $469 a year -- and you still have to pay extra for guests.

Cardholders also get access to the new Sapphire Lounge®, which currently has only six locations. We recently stopped by the Sapphire Lounge® at Boston Logan, and let me tell you, it was luxe.

I have no reason to switch cards anytime soon

Chase has kept me pretty happy for eight years running. So long as I keep getting my annual fee back several times over, I feel no need to downgrade to a card with a lower fee.

That said, I'll continue to keep an eye out for exciting sign-up bonuses and other reasons to switch up my main spending card -- as should you.
