I can't post when little eyes might see what I write....the plane trip is a SURPRISE!
I used Allegiant Air. Tickets as low as $29 one way! The airports were TriCities/Orlando Samford/Knoxville.You may book online (for a fee), use the call center (for a fee), or go in person to the airport and purchase tickets (no charge for this). We ended up doing all three ways! The final purchase was made by calling, so I had to pay $14.00 per ticket for this "privelege"....
What I learned, if you are watching your pennies:
Prices fluctuate, big time. I had been doing my research and saw prices change four times in one day, both up and down in price.
They charge for checked bags, $15 for the first bag, and more for extras. If you need to add a bag last minute, you have until 4 hours before your flight to do so, or they charge you even more than the original $15.
Online they ask you for your seat choices, and I had to fiddle around before I figured out all the extra charges they had tacked on. When I called the center (on another matter), she told me you do not have to choose. The booking folks will assign you, and they do not split up parents from children, so we are okay there. If you DO choose your seats, the prices range from $10 and up per seat. See how fast all this can add up??!!
Something to keep in mind: the local airport sold all of their $29 seats, so I simply picked the next closest airport that had $29 seats. This makes us fly out of one and arrive home at another. As this is no longer a round-trip flight, there were....surprise, surprise....additional segment fees! Which I would have had to pay online, but were waived when I used the call center.
Taxes add up. Airfare was $215(4 tickets) Fed, 911, PFC fees were another $62.
Allegiant does not fly to MCO, so you cannot use Magical Express transportation. But I found some good last minute rental deals. I have not booked this yet, but so far it looks like $135 for a midsize for a week. There are some codes out there, too, that I have not tried applying.
I will post when I get back and let everyone know how it went with the airline.
