No, they're not the only operator who requests a different level. But most vary by a couple of thousand feet only ie. Filed 350 request 370. I can understand these variations could be down to load factors - and that's totally understandable and forgiveable. However filing 270 from EINN to LFOB then requesting 390 cannot be put down to any other reason than slot busting. The stupid thing is there often aren't restrictions higher anyway, RYR just thought there would be!
