Airlines are on a quest to help their customers plan every part of their travel experiences. There has been a big push in recent years among airlines to help customers enjoy integrated travel experiences by partnering with hotel chains. Most reward programs are pretty fluid with how and when members can accumulate and apply earned miles. This means that members can usually mix and match when it comes to applying their earned points from hotels and flights toward booking hotels and flights.

Partnerships between airlines and hotel chains have historically been extremely beneficial for people who travel often. In addition to valuable reward points, customers get to enjoy familiarity, predictability and the backing of a major airline when booking hotel accommodations around the world. Here, we at explain 5 of such airline-hotel points sharing partnerships so that you'll have a better idea how you can utilize these to your benefit.

1. United Airlines

United has partnered with Marriott to help travelers enjoy comfortable accommodations every time they land at a destination. Travelers will have to belong to both the Marriott Rewards program and the United MileagePlus program in order to qualify. The big perk of signing up is that users get a discount of 20 percent every time they convert hotel points to MileagePlus miles. In addition, miles automatically increase by an extra 10 percent when customers redeem points for exclusive RewardPlus travel packages.

2. Virgin Atlantic

Virgin Atlantic breaks down hotel partners into two categories. Customers can either choose to stay at an earning partner or a spending partner. This means that booking a stay at a hotel that's an earning partner will help travelers accumulate redeemable air miles. Staying at a spending partner means a traveler can pay for their stay using reward miles they've already earned.

Virgin Atlantic's extensive list of earning partners includes hotel chains like Best Western, Hyatt, Mandarin Oriental, Radisson, the May Fair, Millennium, Starwood and Marriott. The airline's list of spending partners is far more concise. Customers can redeem points for stays at hotels by Gitcombe, Hilton, InterContinental and Kaligo.
