Thank you. The flight is at 8:15 AM and I have found that it is an Airbus320. We have just decided to go with their requirements so as not to have any trouble. A lot of people on other sites are saying they don't check that closely but we don't want to take any chances. Funny, all this stress about a flight that is just over an hour long! I've spent more time than that this morning just researching it! I'm glad we found out now instead of at the airport and having to pay an exorbitant over limit fee!

One more question since you are being so helpful. If I'm understanding right, we will have to pay a fee to have our carryon in the cabin, right? Otherwise it is checked and placed in the cargo hold?
