Bags........usually $25 each, each way
I paid for seats once and then didn't get the ones I paid for, so won't do that again.
We bring our own food on board or eat at the airport, I don't pay for food.
I always try to get JetBlue for my flights, so 1st bag is free, and I've been upgraded for free a few times to the extra legroom seats. I'm way too cheap to pay for that stuff too! I'll buy snacks in the airport to take onto the plane with me, although if its some kind of celebratory trip, we may have a glass of wine on the plane ($)
I just got home from a trip yesterday. I paid for luggage ($25 each way), but won't pay for seats or snacks/drinks. I bring those with me, and fill up my water bottle before boarding the plane.
When I lived with my parents I always did. Last year my college's apartment complex had a contest. My roommates and I carved a Dr. Who pumpkin. Won 3rd place and $50 to Wegmans!
I'm trying the cookie cutter style this year. I only have a martini glass and a couple dinosaurs to work with.
We have to pay for our extra luggage I over pack so that doesn't help. But I have not yet traveled on an airline where we have to pay for a blanket, pillow, snacks,..... If I wanted a blanket or pillow, I would pay for it. But if I knew ahead of time that they charge for snacks, I would get something before boarding the plane.
I have tried it, not very good at it. DH however is quite good...........and has a lot of books and paper.
One vacation, he even left the room tip in in different patterns (he has a book for dollar bills)
