Hi,
I am laurent, I join your community to get some explication about airfare rules.

The last flight I did was cancelled, Air france give me 2 voocher 2x800€ for the next flight (allowed air france or KLM). I am now looking for the next flight (3 peoples).

I would like to go to central americas in july.

I was looking for round trip on air france's website (about 1000€) :
TLS-MGA-TLS (380€+669€) 02/07/15 until 28/07/15
TLS-SJO-TLS (637€+331€) 02/07/15 until 28/07/15
TLS-PTY-TLS (653€+315€) 02/07/15 until 28/07/15

The price is a bit expansive with round trip so I would like to combine low fare of the first segment TLS MGA and the second segment of SJO-TLS or PTY-TLS.

I try open jaw but it doesn't work well on ita matrix (for the same flight shown below).
TLS-MGA and SJO-TLS (1238€)
TLS-MGA and PTY-TLS (1324€)

On air france's website :
TLS-MGA 02/07/15 (AF7529, AF682, DL369) and SJO-TLS 28/07/15 (CM796, AF475, AF7522) => 701€
TLS-MGA 02/07/15 (AF7529, AF682, DL369) and PTY-TLS 28/07/15 (AF475,AF7522) =>1044€

For the first it works but not for the second that's strange because the segment SJO-TLS have the same flight AF475,AF7522.
