No, because you don't have a BP/reservation for FRA. And your reservation will most likely be cancelled by the time you land in FRA due to an incorrect No Show, so no chance of collecting miles at all.

I was in a similar situation, although it didn't involve a wrong plane. I had flown out of Vienna on Austrian but 10 minutes before landing, we were told the airport is closed and we waited at the nearest designated one to see if it would reopen. Well, after an hour, they decided to fly us back to Vienna and gave us hotel vouchers and had already rebooked us on a morning flight. However, that flight coupon was already used, so I don't know what they did and the following morning we had to get the boarding pass from an agent - I thought at the time that it was a paper ticket but it wasn't. So, the airline is responsible to get you to the destination you picked. Ultimately, it may be your mistake but it was their fault for allowing you on a plane you were not supposed to be on. But don't expect anything beyond getting a flight to your ultimate destination as opposed to extra miles or anything else.

I was once travelling from Canaima to Ciudad Bolivar in Venezuela. The 'airport' in Canaima was basically just a landing strip and a café. My boarding pass was a hand-written ticket and the pilot of the four-seater came to find me to board me. As we landed, I saw the airport sign for Ciudad Guayana and realised that I had travelled to the wrong place. I tried to explain this to the military personnel as I waited on the runway in very poor Spanish. Eventually I managed to board another tiny plane to the correct airport, which was luckily only 15 minutes away.

I once accidentally used a BP for the wrong DATE. I had taken the same flight number two months earlier and pulled out the old BP. I got through security (the TSA agent scruntinized the BP but didn't catch the wrong date???). When I presented it to the GA, the computer beeped. The GA stopped, said your new seat assignment is "xxC", marked it on the BP, but never realized the BP was for the wrong date.

If you get the security/boarding process correct 99.9999998% of the time, the hallowed 6 sigma, it will fail several times a year.

And I highly doubt, with so many humans involved in the process, that it's anywhere near 6 sigma defect free.

Stuff happens.

I once got on the (correct) plane w/o my BP being scanned. The GA took my BP and was about to scan it but got distracted and made an announcement. He then handed me back my BP and waived me on. I didn't see it scanned but thought maybe he scanned it and I didn't notice it, so I just went on. After boarding, the same GA walked to my seat to visually confirm that I was on since my BP hadn't been scanned. If not all GA's do visual confirmations for missing pax then this could be one way a pax gets on the wrong plane.

At JFK T8 American Airlines has some oddly configured gates. After the GA scans your boarding pass, you enter the passageway which then splits to two different gates; there is usually an agent directing you to the correct flight.
On one trip, the agent was directing pax to the wrong gate (until I informed him of his error:p.)
Of course with lots of gates, why would they have two flights departing at (approx.) the same time using such gates.:confused:
[Once there were TSA checking tickets for pax on one flight but NOT the other.:confused:]

ORC only, my friend.:D

I saw this happen last night. And all of us who were correctly on the plane were more than a little scared. Unfortunately for the person on the wrong flight, he was of a certain ethnic group that would be the first to be considered by many Americans in the case of subterfuge.

I'm now pretty sure it was all an innocent mistake.

Bottom line was that we would have taken off with this guy (AA out of IAD) if it weren't for the fact that he was in someone else's seat.

The problem seemed to happen because his name was so similar to the woman who had that seat, that the ticket agent before security checked him in as her. And even checked luggage for him on her ticket. She checked in online and checked no bags. So once this all came to light, he and his carry-ons and checked luggage were all removed from the plane and all was good.

I wish I knew the two names, but I don't know either, unfortunately. By looks, it was hard to imagine how their names could be so similar.

Next, the guy potentially never realized this mistake as he had virtually no English. He was probably pointed toward the gate, and could never tell where the plane was going. I don't know where he wanted to go.

I started reading this thread to see if anyone else here on FT was on that flight. And I found a very good point here: not only did the ticket agent screw up, but security (TSA) missed it also. And the AA scanners missed it too - two of the same boarding passes were scanned without a problem? One was on a phone (the woman's) but still - seems like a big hole if two people can jump on a plane with the same boarding pass. Buy a cheap ticket instead of an expensive one, get through security, board with your friend on a different flight with a copy of their boarding pass (easy to reprint), and check the seat map to make sure you get an empty seat.

Yes it can still happen. The electronic checks are only as good as the humans who use (or ignore) them.

I was flying to Newport News VA with a very tight connection in CLT. The first leg was delayed arriving so I checked the departure board and sprinted to the gate. As I arrived, they were closing down boarding. I handed my boarding pass over and she had trouble scanning it. She told me to go on and she would handle it. Even though it was rushed, she made sure to get in enough moaning about how I should've been there earlier and was causing the flight to be late, etc.

It was something like a Dash 8 so I handed off the bag to the ground crew and boarded. Someone was in my aisle seat and refused to move. The FA just told me to take an empty seat so we could go. I sat, doors closed, and she began her announcement about today's flight to Richmond. I stood up to say I was on the wrong flight but was told I needed to sit and wait until the announcement was done.

After someone got my carry-on from the cargo hold, I walked back to the terminal. The gate agents were still on the computer by the door. When I came in, I had to ask for my BP back and pointed out it was the wrong city. Being US Airways, they took the opportunity to yell at me and complain again.

Another passenger told me that the first flight out of the gate had been delayed. While boarding was going on, they changed the main podium sign over for the next flight (mine).

So yes, even native English speakers can board and be allowed to board the wrong flight.

A little perspective (on the same topic) from 2007-2008

Happened to me a year ago in Panama. I got the right gate, but the jet bridge weirdly split off into Gate A and Gate B halfway down. Accidentally took a wrong turn and ended up on a plane to MIA instead of UIO. Luckily I was sitting in someone else's seat or I would never have caught my mistake.

I used to see this occasionally on Continental especially at IAH. The error would be uncovered when a second pax showed up for the same seat. The FA would examine both boarding passes and redirect the other pax to his aircraft.
It bothers me a bit when they ask Mr. XXXX to ring your flight attendant call button to let us know if you are on this aircraft. They don't know? Pitiful.

In fact this issue has no reflection on any 9/11 situations, or anything else that may have security issues. Assuming everybody airside has been screened then the destination of the plane you board has no relevance to any matters pertaining to safety and security. It's just a matter of ending up at the wrong destination.

There's at least one UA gate at SFO like this. I was boarding a flight to IAD and apparently the person directing folks at the split got called away for something. FAs made an announcement once they found out and a few people got up, but it was a red eye, so who knows what happened if someone sat down and went right to sleep.

Wouldnt a simple passenger count/passenger manifest check tip off the flight crew that something's not right?
