I suspect following this airlines will avoid the area totally.

One can hope. Unsure | :~

I would agree with you but then we both would be wrong.

Four web browsers(opera, safari, firefox, chrome) reports the answer to the following calculation *incorrectly*:

((54/31)+140)

Those 4 browsers return the value : 141.74193548387098
IE reports the value of : 141.74193548387097

Note:The two leading #s in the next example are just for alignment.
if you calculate 54/31 using javascript and browser you get:
##1.7419354838709677

The second one calcs the same equation and simply adds 140 ((54/31)+140) -- to change precision.
141.74193548387098

Notice the digit after the last 9 in the sequence. The rounded up value should be a 7 (round up from 6), but it is reported as an 8 in every browser except IE. You can also compare the value to Windows Calculator for 54/31.

Windows calculator gives : 1.7419354838709677419354838709677
Interesting?

Here's the HTML / JavaScript so you can copy / paste and try in all browsers:

<!DOCTYPE html>

<head>
<meta http-equiv="content-type" content="text/html; charset=iso-8859-1">

<div>Clicking the [Calc] button runs two calculations and shows the result on this page. First calc is: (54/31)</div>

<p id="p1">

<p id="p2">

<div id="extra" style="color:blue"></div>
<input type="button" value="Calc" onclick="DoCalc()"/>
<script type="text/javascript">
var p1 = document.getElementById("p1");
var p2 = document.getElementById("p2");
var extra = document.getElementById("extra");

function DoStart()
{
    testdiv.textContent = "started";
}

function DoCalc()
{
    p1.textContent = "";
    p1.textContent += "##" + 54/31;//calcObject1.y / calcObject2.x;
    var outval = ((54/31)+140);
    p2.textContent = outval.toString();
    extra.textContent = "Notice the digit after the last 9 in the sequence.";
    extra.textContent += " The rounded up value should be a 7 (round up from 6), but it is reported as an 8 in every browser except IE.";
    extra.textContent += "  You can also compare the value to Windows Calculator for 54/31.  Interesting?";
}
