I am looking to buy a ticket with Southwest to Havana. I will be going on to Mexico with another airline rather than returning to the US and getting another flight to Mexico. This will save time and money. I have not seen it listed anywhere that a roundtrip ticket is a requirement but can you confirm. I will have an onward ticket to show authorities and to enter on the visa form. I am wondering if Health insurance is included in Southwest's ticket if only one way into Cuba? Will I have any issues using the link for the visa if not buying a round trip. Thanks!
