Bootstrap grid border issue - html

Question

I've following grid system showing flight information (10 columns) and select button & price (2 columns). I am trying to make a border which would separate select button section from rest of flight information, but when I apply border CSS rule, it draws line only half of the way. I suspect that might be a problem of my row/column structure. How do I resolve current issue?
Thanks for any help!
Outcome:
CSS:
.selectButtonColumn{
border-left: 1px solid;
}
HTML:
<div class="container well well-md searchResult">
<ul class="list-group">
<li class="list-group-item">
<div class="row">
<div class="col-md-10">
<div class="departFlyRow">
<div class="col-md-2 col-md-offset-2">
<div><b>06:20</b></div>
<div>LHR</div>
</div>
<div class="col-md-2">
<i class="btn btn-default"><i class="glyphicon glyphicon-plane gly-rotate-90"></i> </i>
</div>
<div class="col-md-2">
<div>5h 30</div>
<div>direct</div>
</div>
<div class="col-md-2">
<i class="btn btn-default"><i class="glyphicon glyphicon-plane gly-rotate-90"></i> </i>
</div>
<div class="col-md-2">
<div><b>12:50</b></div>
<div>SVO</div>
</div>
</div>
<div class="clearfix returnFlyRow">

I would probably put every 12 columns worth of content in separate row, BUT, I don't think you need to do that to achieve what you are after. Try putting a right border on your "returnFlyRow" class.
.returnFlyRow{
border-right: 1px solid;
}
