The Giants will be tripping in 2017.

This season, they play the AFC West and NFC West, meaning they will be making cross-country excursions so often their frequent-flyer miles could get cashed in and pay for some of (but hardly all of) Eli Manning’s salary. The Giants already know their 2017 opponents and where they will be playing them; when the schedule comes out later this month, they will find out the dates for the games, which will determine if they are able to go forward with Ben McAdoo’s wishes for the team’s travel plans.

The Giants have two games on the West Coast – against Oakland and San Francisco – plus one game in Denver and another in Arizona. They made a formal request to have two of the games – Oakland and San Francisco would be ideal – scheduled in back-to-back weeks.

“You can put in requests, but nothing is guaranteed,’’ McAdoo said recently at the NFL owners’ meetings.

If the Giants get the back-to-back games, McAdoo said “there’s a possibility’’ he would ask ownership to allow the team to stay on the West Coast for the entire week between games. They would find a suitable practice site and save on travel wear and tear. A week-long road trip is a considerable expense, but if the head coach deems it important, it is highly unlikely John Mara and Steve Tisch would deny the request. It is believed McAdoo is heavily leaning to keeping the Giants away for an entire week if the schedule offers that opportunity.

Back in 1998, head coach Jim Fassel opted to stay out West when the Giants were scheduled for a Monday night game in San Francisco and a game six days later in Tempe, Ariz. The Giants went to Tucson to practice for the week. They lost in San Francisco 31-7 and then beat the Cardinals 23-19.

In addition to the cross-country trips, the Giants also will play in Tampa and against their NFC East rivals in Dallas, Washington and Philadelphia. Their home games are against the Chiefs, Chargers, Rams, Seahawks and Lions in addition to the Cowboys, Redskins and Eagles.

Eli Manning finished up his passing camp at Duke University on Wednesday. Joining him were receivers Brandon Marshall, Sterling Shepard, Tavarres King and Roger Lewis, tight ends Will Tye and Jerell Adams and running back Shaun Draughn. The players also played basketball and posed for pictures with Duke coach Mike Krzyzewski. Odell Beckham Jr. did not attend because he had oral surgery scheduled.
