Hello,

I was looking at the "availability" of a flight and it says the following.

R1 X1 N4

Does this mean there are 6 seats left? What do the different codes mean? I assume they are ticket classes but do not know if they are high/low. This is for a crj flight that leaves in 3 1/2 weeks.

I will not know until next week if I have to book it or not. Can someone help me determine if I should book it now before it goes up and risk eating the $100 change fee if I do not take the flight?
