ORLANDO, Fla. — Kristaps Porzingis was slated to be part of the Joakim Noah dinner Friday night. But Porzingis hit major travel trouble — stuck for eight hours on a plane in JFK because of inclement weather — forcing him to land at midnight.

“The worst day of my life, traveling-wise,’’ Porzingis said.

However, by the time he landed, all was right in the world. By that time, Noah had agreed to terms to play alongside Porzingis in the Knicks’ frontcourt.

Porzingis was flying high from the Noah and Derrick Rose additions after he returned from Latvia on Thursday. Seeming more upbeat than two-and-a-half months ago, when his season ended prematurely with a shoulder injury, Porzingis was at Amway Center to watch the Knicks’ summer-league opener.

“Those are really good additions to the team,’’ said Porzingis, who couldn’t contain his smile during his press conference, which came before the Knicks locked up Courtney Lee on a four-year deal. “They will help us win games for sure. Honestly, I can’t wait for the season to start already. Watching videos back in my room, oh man, I can’t wait to get back on the court, especially now we have new additions and [will] be better as a team.’’

The Knicks finally have a penetrating point guard who can provide Porzingis easier buckets. He already is salivating thinking about Rose slashing into the lane and can’t wait to play at a higher tempo. He said the club was too “static’’ last season in the triangle, likely referring more to the Kurt Rambis reign.

“One thing I’m already imagining, he’s a point guard who loves to drive and be explosive,’’ Porzingis said. “After he’s missed layups, I can get those putbacks. That’s one thing I’m thinking about already. I know he’s a great passer, and when he slashes, he can give you the pass and kick-out for the 3-pointer. You got to be ready for a guy like that with those quick passes he makes. You got to be ready to make the next play or shoot the ball.’’

Knicks president Phil Jackson said he hopes Noah will be a terrific influence on Porzingis, too, which is why he invited him to the dinner meeting.

“I think that this guy [Noah] will be a good mentor,’’ Jackson said. “I think he has an ability to coach him in his own regard as a player-to-player type situation. He’s partnered up with Pau Gasol a couple years in Chicago, and I think those things are telling in a young guy’s education in the NBA.’’

Porzingis paid his respects to former teammate Robin Lopez, shipped to Chicago in the Rose deal.

“I loved playing with RoLo — it was really good to play alongside him, a big center, physical,’’ Porzingis said. “And Noah is very similar, very good passer, high-energy guy and I love playing with guys like that [who] get on other people’s nerves. He’s that type of guy. We can have a very good connection.”

Though he will be in his second season, Porzingis said he already is tired of losing and loves the idea of going for broke now with Carmelo Anthony, Rose and Noah edging toward the end of their primes.

“I’m young, but we don’t have 10 years to win a championship,’’ Porzingis said. “We got to win soon. That’s my mindset as well. Those guys want to win right away. They’ve been in the league a long time. All I got to do is stay as mentally focused as I can to help those guys win. I’m not here to have five seasons of trying to win.’’

Though Porzingis, second in the Rookie of the Year voting, has been in Latvia since soon after the season ended, he has worked diligently in the gym with brother, Janis, a former European professional player.

“I’ve been working a lot on my handle,’’ Porzingis said. “It’s really annoying. All the little drills with my brother Janis. I can feel it day by day, I’m getting better. And shooting a lot. Shooting so much it’s annoying.’’

Porzingis has gained five pounds since the regular season ended, but strength in his core is now a bigger goal rather than added pounds. He said he was too heavy in his opinion when he entered his rookie season after bulking up by 11 pounds. Porzingis, who met new coach Jeff Hornacek for the first time, will work out with the summer team but not play.

The Knicks’ summer-league team opened in disastrous fashion, losing 81-49 to Detroit, shooting 29.9 percent. Wichita State’s Ron Baker, slated to get a training-camp tryout, shot 1 of 9 with three turnovers.
