airlines in CA

I need your advise on air connections in CA

I might opt for flying from one country to another during my trip to CA.
Can you recommend some airlines which operate on following routes:

CostaRica-Nicaragua
Honduras-Nicaragua
Maxico-Nicaragua
Mexico-CostaRica

Price is a priority.

Thanks in advance!

Check copa, taca, nature air, for the shorter central america flights.

Then also american, delta, and continental also serve those areas too.

Flights within CA are VERY expensive. Almost everyone uses the bus system. There are two that I have used, Tica BUs and King Quality. Both are nice. King quality is the more expensive of the two and therefore is less crowded. They give you a blanket and pillow and food along the way. Ours was from McDonalds. Tica is less frills but still a good bus ride. My only suggestion is to keep a jacket close as the buses get VERY cold some times. They both have web sites. This is the only way to go if you have any concern at all about money. It is actually cheaper sometimes to fly back to the sates and then back to CA rather then doing a country to country flight.

transporte del sol is another that i have used besides the two above and have used all three between guatemala and nicaragua.
