I think this is a pretty funny episode. Not the best but its good.
I find it very sad that Chandler and Monica don't seem as in love as they should be. I love their pairing but when they are at the airport it really is like they don't love each other that much. Especially the "We have to have the free stuff" part. I am disappointed.
The highlight of this episode for me is when Rachel actually tells Ross. Ross has the most hilarious reaction.
As this is all happening Phoebe and Joey devise a plan to get into Chandler and Monica's apartment which until near the end, it backfires on them.
I really think if the events of 9/11 didn't occur and they used the original Monica/Chandler footage, it would've made the episode a lot better.
