すみません、この大きな荷物はどこに置けばご迷惑になりませんか？

Excuse me, where can I put this large luggage without bothering anyone?

恐れ入りますが、ドア付近のスペースか、座席の前の足元でしたら比較的邪魔になりにくいかと思います。
おそれいりますが、ドアふきんのスペースか、ざせきのまえのあしもとでしたらひかくてきじゃまになりにくいかと。
I apologize, but I think it would be relatively less of a bother near the doors or on the floor space in front of the seats.
Gesture & etiquette
Point to the luggage, look around for space, make a questioning gesture.
Do not block aisles or emergency exits. Be mindful of other passengers, especially during peak hours. Avoid placing large luggage on seats.
