Looks as if your boy Al Gore, along with the box-top cereal decoder ring failed you. Is the "Tin-Foil Cap" still on?? Since your so keen to know where I'm based, it's actually IAH.....No secret.....made that available in past-posts.

Regarding your question.....I wouldn't know about B757 fuel stops out of IAH, we don't fly that a/c outta IAH to Europe....Only the 767 & 777. Since your curious on the topic of fuel stops & pay, it goes a little something like this.....

Just as you "r"UAL Pilots get paid by the minute, so do we. Here's the kicker.....When I was based up in EWR doing a lot of BCN & TXL X-ings, it was not uncommon to show up in Ops for the return leg from Europe to find a "scheduled fuel stop" added to the release even before you departed to head Westbound. The beauty/rub of the deal resulting from that is a 'mid-sequence modification' (IE-a scheduled stop for gas/additional 'leg' added after the sequence had already started), it just meant 150% pay on ALL "OVERS" resulting within that sequence, this is a contractual clause. Of course, Jeff and his minions require pilots to submit a pay-claim to get the 150%, just another hoop in the POS CBA. The added bonus was this situation was an additional landing came about producing 3 landings in the pairing. Most of the "good Captains" would give the IRO the 'odd' landing which made it nice to the 'professional IROs' to grab a bounce.

To recap your Fuel Stop Question......
1) General Overs on unscheduled stops, not a bad thing.
2) Mid-Sequence Mods resulting in 150% pay on 'overs', even a better thing.
3) IRO's getting a chance to swing a landing in the deal depending on the Capt.....Doesn't get much better.

Well, I'll say we've drifted this thread straight into the ground, but I hope that quenches all of your questions regarding the topic. As you can see....These fuel stops DON'T cause you to LOOSE pay, quite the opposite.....plain and simple.
